Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything. Simplify the LHS by first getting a common denominator of sin(x)*(1 + cos(x)). LHS becomes: [(1 + cos(x)) - sin²(x)]/[sin(x)*(1 + cos(x))] = [(1 + cos(x)) - (1 You can put this solution on YOUR website!
