Question

prove that cos theta sin theta - sin theta cos(90- theta) cos theta/sec(90- theta) - cos theta sin(90- theta) sin theta/ cosec(90- theta)= 0​

Answer 1

Here's ur answer.....

Hope u understand it!

Answer 2

ans is zero

formula

sin(90*-@)=cos@

cos(90*-@)=sin@

sec(90*-a) =cosec @

cosec(90*-@)=sec@
