By using the substitution u = sinx or otherwise, find. Giving your answer in terms of x. From C3 you should remember that: sin2x = 2sinx cosx . Hence: If u = sinx du = cosdx (part of the integral!) Therefore Example 2. Use the substitution x = sin θ to find the exact value of. If x = sin θ then the denominator becomes (1 – sin2θ) which is ... ................
