I've been working on those integral questions, but am having a problem if entering the way CM wants, helpI

V64 - 22 Evaluate the integral: dx 3x2 (A) Which trig substitution is correct for this integral? Ox = 8 sin(0) Ox = 8 tan(0) Ox = 64 tan(0) Ox = 8 sec(0) Ox = 64 sec(0) Ox = 64 sin(0) (B) Which integral do you obtain after substituting for a and simplifying? Note: to enter 0, type the word theta. do (C) What is the value of the above integral in terms of 0? + C (D) What is the value of the original integral in terms of ac? + C/ 202 49 Evaluate the integral: dx (A) Which trig substitution is correct for this integral? Ox = 3 sin(0) Ox = 7 sin(0) Ox = 7 sec(0) Ox = 49 sec(0) Ox = 49 tan(0) Ox = 7 tan(0) (B) Which integral do you obtain after substituting for a and simplifying? Note: to enter 0, type the word theta. (C) What is the value of the above integral in terms of 0? + C (D) What is the value of the original integral in terms of ac? + C
