Steve uses the trignnometric substitution tan ()to evaluate / e) de After simplification, the integral evaluates to i sec (8) – 3 sin (8) +Cusing this substitution Whichof the following is a proper representation of the solution in terms of.x?

Q: Evaluate S₁ 45 dx 1- cos (9x)

A: To evaluate .

Q: √√3 tan-¹x 4. (10 points) Evaluate SY 1+x2 dx (using substitution).

A: The value of the integral is 7 pi^2 / 288.

Q: 2t True or False, for all values of x, 2 dt = sint O True O False 2x sinx

A:
