Question

Find relation between a and B if sina = sinB​

Answer 1

Answer:

convert both of them into cosec A

Answer 2

Sin A = Sin B

Sin A - Sin B = 0

TAKING Sin AS COMMON:

Sin(a-b) = 0

A-B= 0/Sin

A-B=0

A=B

Hence proved....

I took so much of time coz i was not getting with which method i shall prove this...

It was so easy

Sin A = Sin B

Cancelling sin from both sides

A=B

DONE!!

thnx
