1) [Techniques of Integration] (3 marks) Evaluate the following integral by using one of the following methods: 0 Substitution / Change of Variable and Inverse rI'rigonometric Substitution: include the choice of u and du, the calculation of the new limits of integration (if applicable), and the substitution into the original integral before you evaluate the integral. 0 Partial Fractions: you must include how you found any constants before you evaluate the integral. 0 Integration by Parts: include the statement of the general IBP formula, choice for f (cc), f'(:c), 9(55), g'(:c), and the substitution into the IBP formula before you evaluate the integral. You must show all the steps toward your solution, and reference any identities you used. 4 facgex dcc @
