UdemyTrigonometry - The Unit Circle, Angles, & Right Triangles
4.7(949)3k students
UdemyDesigned for high school and college students who need a solid grip on trigonometry, this course covers fundamentals through advanced proofs and applications. You'll learn angles in standard position, convert between degrees and radians, work with coterminal and reference angles, and master the unit circle and all six trig functions.
The course covers right-triangle applications (SOHCAHTOA, 30-60-90 and 45-45-90 triangles), graphing sine, cosine, tangent, and their reciprocals, inverse trig functions, and real-world word problems involving bearings and angle of elevation/depression. It wraps with identities—sum/difference formulas, double-angle and half-angle techniques, and verification strategies. Whether you're prepping for a test or filling gaps in your foundation, this is comprehensive.
