Question

Sine cosine tangent cosecant secant cotangent formulas

Answer 1

Let @ be theta.
$\red{\sin(@)=\frac{P}{H}\\\\ \cos(@)=\frac{B}{H}\\\\ \tan(@)=\frac{P}{B}\\\\ \csc(@)=\frac{H}{P}\\\\ \sec(@)=\frac{H}{B}\\\\ \cot(@)=\frac{B}{P}}$
(csc) means cosec.

TRIGONOMETRIC FUNCTIONAL IDENTITIES
sin²x + cos²x = 1
1 + tan²x = sec²x
cot²x + 1 = cosec²x

TRIGONOMETRIC FORMULAS
sinx = opposite/hypotenuse
cosx = adjacent/hypotenuse
tanx = opposite/adjacent
cosecx = hypotenuse/opposite
secx = hypotenuse/adjacent
cotx = adjacent/opposite
