Find the indefinite integral. (Note: Solve by the simplest method—not all require integration by parts. Use C for the constant of integration.)

\int 9arctan x dx

\int 9 arctan x dx

Step-by-step explanation:

To find you must:

Step 1: Apply the constant multiple rule with c = 9 and

Step 2: For the integral , use integration by parts

Let and .

Then

and

The integral can be rewritten as

Let

Then and we have that .

Therefore,

Step 3: The integral of is

Step 4: Recall that

Therefore,

Step 5: Add the constant of integration
