Grade 12 gradeMath subjectFree quiz

Grade 12 trigonometric functions extend right-triangle ratios to the unit circle, radians, and graphs of sine and cosine. Students use reference angles and quadrant signs (ASTC), invert sine or cosine on a restricted range, and model periodic phenomena. A full rotation is 2π radians, which equals 360°.

What you practice

These are the Grade 12 Trigonometric Functions skills this quiz is built around.

Convert between degrees and radians and evaluate sine, cosine, and tangent at common angles.
Use the unit circle and reference angles, including negative and coterminal angles.
Describe amplitude, period, and phase shift of y = a sin(b(x − c)) + d.

A useful tip

Radians measure arc length on the unit circle: θ = s/r. To convert degrees to radians, multiply by π/180, not by 180/π.
