Expand the Trigonometric Expression sin(2y) sin (2 y) sin (2 y) Step 1. Apply the sine double-angle identity. 2 sin (y) cos (y) 2 sin (y) cos (y)

cos(2x) = cos 2 (x) − sin 2 (x) = 1 − 2 sin 2 (x) = 2 cos 2 (x) − 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures.

Trigonometry mainly provides six functions for sine (sin), cosine (cos), and tangent (tan), also its reciprocal functions cosecant (csc), secant (sec), and cotangent (cot). These processes help …

sin ^2 (x) + cos ^2 (x) = 1 tan ^2 (x) + 1 = sec ^2 (x) cot ^2 (x) + 1 = csc ^2 (x) sin(x y) = sin x cos y cos x sin y cos(x y) = cos x cosy sin x sin y

A basic trigonometric equation has the form sin(x)=a, cos(x)=a, tan(x)=a, cot(x)=a
