Question

Is there any way out to learn the formulas of trigonometry asap? My exam is on my way and I'm not prepared for it at all. ​

Answer 1

Answer:

Formula

Sin^2A+cos^2A=1.........(1)

Divide this eq. with sin^2A

1+cot^2A=cosec^2A

Now divide eq.(1) with cos^2A

tan^2A+1=sec^2A

Remember the (1)eq.

Other formulae

sinA/cosA=tanA

cosA/sinA=cotA

1/sinA=cosecA

1/cosA=secA
