Evaluating an Improper Integral In Exercises 33–48, determine whether the improper integral diverges or converges. Evaluate the integral if it converges, and check your results with the results obtained by using the integration capabilities of a graphing utility. ∫ 0 π / 2 sec θ   d θ

To determine
Whether the improper integral 0π/2secθdθ converges or diverges.

Explanation

Consider the provided integral,

0π/2secθdθ

Now, use the formula:

abf(x)dx=limcbacf(x)dx

Then,

0π/2secθdθ=limb(π/2)0bsecθdθ

Now, apply the formula:

secxdx=ln|secx+tanx|
