Tutorial Exercise
Evaluate the indefinite integral.
| tan(5x + 8)dx
Step 1 of 5
In order to perhaps use a substitution, rewrite tan(5x + 8) in terms of sine and cosine.
sin (5x + 8)
sin (5 z + 8)| dx
tan(5x + 8)dx =
cos(5x + 8)
Step 2 of 5
Since the numerator is the derivative of the denominator, except for a constant factor, the substitution form of
the integrand is a du, where a is a constant factor.
Use the substitution u = cos(7x+ 2)
Find du.
du = -7 sin(7x +2)
