Integration Method: U-Substitution and U-Solve
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given.</em>
<em />
<u>Step 2: Integrate Pt. 1</u>
<em>Identify variables for u-substitution.</em>
- Set <em>u</em>:
- [<em>u</em>] Apply Trigonometric Differentiation:
- [<em>du</em>] Rewrite [U-Solve]:
<u>Step 3: Integrate Pt. 2</u>
- [Integral] Apply Integration Method [U-Solve]:
- [Integrand] Simplify:
- [Integral] Apply Arctrigonemtric Integration:
- Simplify:
- [<em>u</em>] Back-substitute:
∴ we used substitution to <em>find</em> the indefinite integral.

Topic: AP Calculus AB/BC (Calculus I/I + II)
Unit: Integration
There are 12 months in a year so if he pays every 4 months, he pays 3 times a year or $522 in total for a year (174 x 3 = 522). If he has pays that for three years it would be $1,566 (522 x 3).
6x + 4y = -24
30x + 20y = -120
You can multiply all of the numbers by any common factor and get an equation that works.
