Integration Property [Multiplied Constant]: 
Trig Integration: 
U-Substitution
Step-by-step explanation:
<u>Step 1: Define</u>

<u>Step 2: Identify Substitution Variables</u>
u = 3x
du = 3dx
<u>Step 3: Integrate</u>
- [Integral] Rewrite:

- [Integral] U-Substitution:

- [Integral] Trig Integration:
![\displaystyle \frac{1}{3}[-cos(u)] + C](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B1%7D%7B3%7D%5B-cos%28u%29%5D%20%2B%20C)
- [Expression] Multiply:

- [Expression] Back-Substitute:

I assume the equation is

then let
.


The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

Then




but again we omit the negative solution, so that
