Answer:

Use of trignometric Identities will help you

Explanation:

1.SinA= opposite side/adjacent side

this can also be written as: 1/CosecA

By 1+Cot^2A= Cosec^2A

so,

SinA= 1/\sqrt{1+cot^2A  - - - - - - (1)

2. SecA= \sqrt1+Tan^2A

so, SecA= \sqrt Cot^2A+1/Cot^2A - - - - (2)

* since TanA= 1/cotA*

3. TanA= 1/CotA
