Dec 8,  · Sample Problems - Solutions 1. Z sinx dx Solution: This is a basic integral we know from di⁄erentiating basic trigonometric functions. Since d dx cosx = sinx, clearly d dx (cosx) = . When in doubt, try integration by parts. As a general rule of thumb, pick uto be an expression easy to di erentiate, and dvto be the most complicated looking term in the integrand that you .

Hint: use integration by parts with f = ln x and g0 = x4. Solution: If f = ln x, 0 1 then f. Also if g0 = x4, then g = 1 x5. Hint: the denominator can be factorized, so you can try partial fractions, but it's much better to look for the derivative of the denominator in the numerator. Techniques of Integration MISCELLANEOUS PROBLEMS Evaluate the integrals in Problems 1— The students really should work most of these problems over a period of several days, even while you continue to later chapters.
