When u change the tan^2(x) to sinx n cosx ,dont forget to square to be b^2/(1-b^2). Then numerator make it to a single fraction .

For the tanx at the denominator, rationalise by multiplying √(1-b^2). U should get 2b[√(1-b^2)] /(1-b^2)

Simplify both the numerator n denominator by cancelling (1-b^2). Then rationalise again
