Solution: We might think just to do Z 3 0 1 (x−1)2/3 dx= h 3(x− 1)1/3 i 3 0, but this is not okay: The function f(x) = 1 (x−1)2/3 is undefined when x= 1, so we need to split the problem into two integrals. Z 3 0 1 (x− 1)2/ 3 dx= Z 1 0 1 (x− 1)2/ dx+ Z 3 1 1 (x− 1)2/3 dx. The two integrals on the ...

Even when the chain rule has “produced” a certain derivative, it is not always easy to see. Consider this problem: Z x3 p 1−x2 dx. There are two factors in this expression, x3 and p 1− x2, but it is not apparent that the ...

2.Consider f(x) = sin(2x+ 7)cos(x2) + cos2(4 x3) x. Find lim x!1f(x), if this limit exists. (Solution)This limit may look daunting, but we need only recall that the sine and cosine functions are bounded. Since sine and cosine take values between 1 and 1, the values of the product sin(2x+ 7)cos(x2) will be between 1 and 1. That is,

Do not conclude that because the sin integral (x) equals cos(x), the integral of sin^2(x) should be equal to -cos^2(x); In fact, the answer contains no cochinus at all. You cannot directly combine sin^2(x). Use trigonometric identities and calculus substitution rules to resolve the issue.
