Sunday Tuition at Woodlands at 2.00pm – Differentiation and Integration of Trigonometry

Differentiation and Integration of Trigonometric Functions is quite a challenging topic. The Additional Math question in the photo is one fine example.

a)  Differentiate the trigonometric function using chain rule.  Don’t forget the differentiate  x2+2x inside the bracket.

b) You are required to integrate the product of two expressions \left( {x+1} \right)\times \cos ({{x}^{2}}+2x). As there is NO product rule for Integration we use the answer for part a to indirectly find the answer.
