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 in solving angle and distance related problems in both 2D and 3D surroundings.

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
