Krista King – Become a Trigonometry & Precalculus Master (Download)
Advanced mathematics forms the gateway to calculus, engineering, physics, and countless STEM careers. Yet trigonometry and precalculus create stumbling blocks for many students—confusing identities, abstract graphing transformations, and complex number operations that textbooks explain poorly. Whether you’re preparing for calculus, strengthening your foundation, or revisiting mathematics after years away, clarity makes all the difference.
Step-by-step instruction transforms intimidating concepts into skills you genuinely understand.
Course Overview
Become a Trigonometry & Precalculus Master by Krista King delivers complete coverage through 302 structured lessons spanning both subjects. Krista’s teaching breaks down each problem from setup through solution, explaining not just how to solve but why each step matters.
The course offers 470+ practice questions across 89 quizzes plus 10 bonus workbooks, ensuring continuous skill reinforcement. Downloadable formula sheets and detailed notes provide quick reference for key concepts.
What You’ll Master
Angles and Trigonometric Functions
Understand angle measurement in degrees, DMS, and radians. Master all six trig functions—sine, cosine, tangent, cosecant, secant, and cotangent—including reciprocal, quotient, and Pythagorean identities.
The Unit Circle
Navigate the unit circle confidently, finding trig values for any angle. Solve right triangles, work with reference angles, apply even-odd identities, and tackle angles of elevation and depression.
Graphing and Transformations
Sketch sine, cosine, tangent, cotangent, secant, and cosecant graphs. Apply period, amplitude, horizontal shifts, vertical shifts, and combined transformations to visualize functions accurately.
Advanced Identities
Work with sum-difference, double-angle, half-angle, product-to-sum, and sum-to-product identities. Prove trigonometric equations and find complete solution sets.
Laws of Sines and Cosines
Solve non-right triangles using these essential laws. Calculate areas with Heron’s formula and navigate the ambiguous case confidently.
Polar Coordinates and Curves
Convert between rectangular and polar coordinates. Graph circles, roses, cardioids, limaçons, and lemniscates in polar form, and find curve intersections.
Complex Numbers
Perform operations with complex numbers, graph them, work with polar forms, apply De Moivre’s Theorem, and find complex roots.
Matrices and Systems
Use matrices to solve systems through Gauss-Jordan elimination, perform matrix operations, find inverses, apply transformations, and use Cramer’s Rule.
Partial Fractions
Decompose fractions with distinct and repeated linear factors, distinct and repeated quadratic factors, and mixed factor combinations.

Conic Sections
Identify, graph, and work with circles, ellipses, parabolas, and hyperbolas. Master rotating axes and polar equations of conics.
Parametric Curves
Understand parametric representations, eliminate parameters, determine direction, and find parametric equations from descriptions.
Who Should Enroll
Current trigonometry or precalculus students struggling with classroom instruction gain clear explanations that fill knowledge gaps. Students preparing to start these courses get ahead with solid foundational understanding. Homeschool parents find comprehensive curriculum support with teaching they can follow alongside students. Adults returning to mathematics after years away rediscover analytical thinking through patient, logical instruction.
