I want to ask question c and f, thanks

54. Using different substitutions Show that the integral
f6x² − 1)(x + 1))-²/³ dx
can be evaluated with any of the following substitutions.
a. u = 1/(x + 1)
b. u = ((x - 1)/(x + 1))* for k= 1, 1/2, 1/3, -1/3, -2/3,
and -1
d. u = tan-¹ √x
f. u = cos ¹ x
c. u = tan ¹x
e. u = tan¹ ((x - 1)/2)
g. u = cosh ¹x
What is the value of the integral?
