Methods of Integration |Integration using Trigonometric Identities Integration by Substitution If we have to evaluate an integral of the type ∫f{Φ(x) Φ'(x)dx then we put Φ(x) =t and Φ'(x) dx = dt. With this substitution, the integrand becomes easily integrable. Case1 When the integrand is of the formf(ax + b), we put (ax +b)= t
