Question

$\infty \csc( \cos(\pi\pi \cos(\% \beta \pi \beta \pi ln(\%\pi \alpha \% log(\%\pi \alpha \pie \sec(e \beta \sec(?) ) ) ) ) ) )$
why cos theta = sin theta.​

Answer 1

Answer:

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 .
