\f2 1. Choose a method suitable for evaluating each of the integrals below. Your possible choices of method here, and the information you must show if you choose that method, are: (i) Direct antiderivative: evaluate (write the antiderivative) (ii) u-substitution: give the substitution (what does u equal)? (iii) Integration by parts: identify which term is u() and which is u'(x) (iv) Powers of trigonometric functions: apply the appropriate trig identity and indicate the substitution that would then be made (v) Trigonometric substitution: give the substitution (what does a equal)? For methods (ii)-(v), just give the information requested, do not evaluate the integral completely
