Question

wat is sin theta and cos theta

Answer 1

SIN (THETA)=a/c
COS(THETA)=b/c
TAN(THETA)=sin (theta) / cos (theta) = a/b

they are mainly trigonometric identities

Hope it helps!!

Answer 2

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse
