If the exponent of tangent is odd, factor off sec(x)tan(x), replace the remaining even powers (if any) of

  2xcos(x2)dx. Let u = x2, then du/dx = 2x or du = 2xdx. Since we have exactly 2xdx in the original integral, we can replace it by du: Z 2xcos(x2)dx = Z cosudu = sinu+C = sin(x2)+ C. This is not the only way to do the algebra, and typically there are many paths to the correct answer. Another possibility, for example, is: Since du/dx = 2x, dx = du ...

  f(x)dx is always zero, because the postive and negative parts exactly cancel. On the other hand, ￿ ∞ b f(x)dx and ￿ b −∞ f(x)dx are always undefined. Do we want the answer for the whole integral ￿ ∞ −∞ f(x)dx to be undefined or zero? There is no intrinsically correct choice here but it is a lot safer to have it undefined.

  dx isn’t defined as a Riemann integral becuase f is unbounded. In fact, if 0 < x1 < x2 < ··· < xn−1 < 1 is a partition of [0,1], then sup [0,x1] f = ∞, so the upper Riemann sums of f are not well-defined. An integral with an unbounded interval of integration, such as Z ...

  The limit comparison test says: The integral I converges iff J = Z ∞ 3 dx ln(x) converges. We need to find out if J converges. We now use the direct comparison test: for x > 0 holds ln(x) < x ⇒ 1 x < 1 ln(x) ⇒ Z ∞ 3 dx x < Z ∞ 3 dx ln(x). Since Z ∞ 3 dx x diverges, then both J and I diverge. C
