Become a Trigonometry & Precalculus Master

) and an additional 10 workbooks with extra practice problems, to help you test your understanding along the way. Become an Trigonometry & Precalculus Master is organized into the following sections:

  • Angles and their measure, including degrees, DMS, and radians

  • Angles in circles, including oriented arcs, circular sectors, and linear and angular velocity

  • The six circular functions, which are sine, cosine, tangent, cosecant, secant, and tangent

  • The laws of sine and cosine, including Heron's formula

  • The unit circle, and how to use it to complete a triangle

  • Graphing the trig functions using period and amplitude, horizontal and vertical shifts, and other transformations

  • Trig identities like even-odd, sum-difference, double-angle, half-angle, product-to-sum, and sum-to-product

  • Inverse trig functions and their graphs

  • Polar coordinates and graphing polar curves

  • Parametric curves and how to sketch their graphs

  • Analytic geometry of conic sections like circles, ellipses, parabolas, and hyperbolas

  • Complex numbers, including polar forms and De Moivre's theorem

  • Matrices for solving systems, Gauss-Jordan elimination, transformations and inverse matrices

AND HERE' We start from the beginning... I explain the problem setup and why I set it up that way, the steps I take and why I take them, how to work through the yucky, fuzzy middle parts, and how to simplify the answer when you get it.

Notes: The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.

Quizzes: When you think you’ve got a good grasp on a topic within a course, you can test your knowledge by taking one of the quizzes. If you pass, great. If not, you can review the videos and notes again or ask for help in the Q&A section.

Workbooks: Want even more practice? When you've finished the section, you can review everything you've learned by working through the bonus workbook. The workbooks include tons of extra practice problems, so they're a great way to solidify what you just learned in that section.

HERE' I feel like I am actually learning something from them. " - Jon K.

  • “The Instructor has an excellent command of the subject material and a great way of presenting it. In addition to that, she has a very pleasant voice that keeps you attentive.” - Robert S.

  • “This is an excellent course to become more familiar with trigonometric equations. The step by step instruction is very is to follow. I found it very helpful to follow along with solving the problems on paper to solidify the learning experience.” - David M.

  • “Krista explains everything in "simplest terms" so even if you haven't worked with this stuff for a while, she makes it totally easy to get back into the swing of it all. Thanks for (another) excellent course. ” - Paul L.

  • “Huge help to be able to review these in a platform much more suited to learning than YouTube.” - Wesley F.

  • YOU'

    I can't wait for you to get started on mastering trigonometry and precalculus.

    What people are saying

    easy to follow

    Personally I gain much knowledge about trigonometry and precalculus and the instructor is very good Easy to follow along, especially appreciate the video examples.

    So far the content is really easy to follow along with, and it really explains the concepts of math in a simple way.

    Your lessons are presented in an easy to follow way.

    Very detailed explanations provided that are super easy to follow.

    I am enjoying the structure of the course and the easy to follow instructions so far.

    Really easy to follow and simplifies concepts It's quite understandable so far even though I'm just starting the course.

    Well explained Excellent instructor and good quality audio and Video She goes over the basic concepts, and is easy to follow along with.

    They’re easy to follow and entertaining while being really informative.

    far so good

    I had to watch the video twice to fully understand what was going on yeah its good So far so good I am thoroughly enjoying the course thus far!

    Perfect pace and suitable detail for those that are not gifted mathematicians So far, the explanations are concise and detailed, and makes the topic very easy Great instructor, quick and to the point Knowledgeable presenter, clear content Seems very thorough so far so good.

    So far so good...simple, clear explanations.

    excellent explanations SO far so good Yes Good Stuff The videos Excellent I'm an adult that didn't receive a very good math education, and Krista King's courses got me up to speed for business school.

    krista king

    This is the fourth course by Krista King that I've completed and once again she's delivered a superb course.

    Krista King is an awesome teacher!

    I get really excited and learning so much, thank you Krista King Krista's courses are the absolute best you can find online, as far as I'm concerned.

    Wonderful, like the other courses by Krista King.

    I have known Krista King way before Udemy and she has been known a very, very nice and very, very good instructor for math, par none.

    Excellent Krista King makes learning fun and easy to understand.

    unit circle

    I had to study section 6 (unit circle) to understand previous sections.

    This course so far is dealing with angle measures (first unit), but working simultaneously in degrees and radians helps familiarize radians and the unit circle early on.

    I thought would start off with more basic information like the unit circle .

    Some quiz questions were all in decimal but the video was using the unit circle with hole numbers and pi, so with the word problem in decimals I couldn't figure out how to get the sin/cos from the unit circle.

    I was hoping for a little more explanation/proofs behind the unit circle and.

    So far, it is serving its purpose on reviewing trig functions, identities, and values on the unit circle.

    high school

    I was able to piece it together after digging deep in my memory going back 19 years to high school math.

    You make math so much easier to understand.I didn't pay attention in high school but you make things click as if I did.

    Especially for a high schooler.

    They are helping me a ton to brush up on forgotten concepts from high school.

    If you remember much of high school math at all, you can skip directly to her algebra courses (which are also excellent).

    feel like

    I feel like it's getting me ready for Calculus; thanks!

    I really feel like I'm learning, and not just parroting examples.

    I feel like I am actually learning something from them!

    I feel like putting the units 4,5,6 in the order 6,4,5 would help a lot She is great at explaining what is going on and making sure we know we know what is what.

    I would also recommend her calculus courses, though I feel like her geometry and trigonometry courses lacked substance compared to the rest of her classes.

    very helpful

    I've always struggled with radians, so this is very helpful.

    This course is really very helpful...The most that I like about this course is that it has all the notes.. and those notes are of very high quality...I really appreciate the hard work of Kristia...Thanks a lot... Krista's teaching style is awesome!


    its very helpful Everything is very easy to understand.

    follow along

    Not only is she well spoken in all of her videos, but her methods of teaching allow for someone with even limited knowledge of a subject to jump right in to any unit and at least be able to follow along no matter the difficulty.

    I found it very helpful to follow along with solving the problems on paper to solidify the learning experience.

    understand what

    A lot so far is review and assumes, rightfully so, that you understand what is being discussed.

    You need to read the notes AND watch the video's to get it all :) It was great.. Good course so far, I notice things being used before they are explained, which throws me off a little and I have to do outside research to fully understand what is going on, but regardless I am still learning which is the ultimate purpose of taking this course.

    Once youtube taught me then I was able to understand what she was talking about.

    quiz questions

    But there are several quiz questions that are worded differently, not to do with the lectures and are written completely different than on video or even in the workbook if you read several of them.

    Also, occasionally there are quiz questions that weren't discussed in the videos, which can be a little confusing at first.

    Also, some quiz questions do not appear to be in the PDF.
