Trignometry


In place of sin A it should be sin theta


@abhisheksingh
Sir in this solution why you multiplied 1+sin theta /1 sin theta with 1+sin theta/1+sin theta.

So that in denominator it becomes in form a^2b^2 w

And finally u get cos^theta in denominator

@abhisheksingh
Sir I m getting problem in understanding this solution because this question is in the form of linear equation therefore both sides(i.e RHS &LHS) shoul be multiplied with 1+sin theta/1+sin theta then why you just multiplied this with LHS but not RHS.

@elizaberthman multiplying and dividing by same thing doesnt change the eqn.
(1+sin@)÷(1+sin@)=1
So we r basically multiplying 1 which wont affect d eqn
