Question

all formulas of trigonometry.

Answer 1

BASIC FORMULAS:
(I would write A in place of theta)
sinA=1/cosecA
cosA=1/secA
tanA=sinA/cosA=1/cotA

Now,
sinA=90-cosA or cosA=90-sinA
cosecA=90-secA or secA=90-cosecA
tanA=90-cotA or cotA=90-tanA

NOW IDENTITIES:-

${ \sin}^{2} a + { \cos }^{2} a = 1$
tan2A+1=sec2A
Cot2A+1=cosec2A

I hope this helps.
