Improper Integrals Questions here are some calculus 1 integration questions, i want a clear solution for those questions only:

problem 26 and 13 in page 333

problem 7a and 13a in page 350

problem 74 and 67 in page 352

42 and 41 in page 372

19 and 6 and 3 in page 459

48 and 9 in page 466

19 and 15 and 5 and 1 in page 479

13 in page 505

i don’t just want solution, i also want explanation for the steps and how you find the answer

i don’t mind handwritten, just make it clear

In Exercises 35 38. guess an antiderivative for the integrand function.
Validate your guess by differentiation and then evaluate the given def-
inite integral. (Hint: Keep in mind the Chain Rule in guessing an anti-
derivative. You will learn how to find such antiderivatives in the next
Section)
