Prove that ` sin ^(-1).(3)/(5) = tan ^(-1) .(3)/(4)`.

Text Solution

Verified by Experts

Let `sin ^(-1).(3)/(5) =theta`
`rArr" "sin theta =(3)/(5) rArr cosec theta=(5)/(3)`
`rArr " "cosec^(2) theta =(25)/(9) " "rArr 1 + cot^(2) theta=(25)/(9)`
`rArr" "cot^(2)theta =(16)/(9) rArr " "cot theta =(4)/(3)`
`rArr" "sin ^(-1).(3)/(5) = tan^(-1).(3)/(4)`
