Lisa [10]
setting things up:<em>
let x be the # of bees in the swarm, then </em>
\frac{x}{5}+\frac{x}{3}+3(\frac{x}{3}-\frac{x}{5})+1=x

<span><em>multiply across by 15</em>
</span>3x+5x+3(5x-3x)+15=15x
8x+3(2x)+15=15x
8x+6x+15=15x
14x+15=15x
15=x\leftrightarrow x=15

Sin (3x) dx = ?<br> find the integral
AVprozaik [17]

Answer:

\displaystyle \displaystyle \int {sin(3x)} \, dx = \frac{-cos(3x)}{3} + C

General Formulas and Concepts:

<u>Calculus</u>

Antiderivatives - Integrals

Integration Constant C

Integration Property [Multiplied Constant]: \displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx

Trig Integration: \displaystyle \int{sin(x)} \, dx = -cos(x) + C

U-Substitution

Step-by-step explanation:

<u>Step 1: Define</u>

\displaystyle \int {sin(3x)} \, dx

<u>Step 2: Identify Substitution Variables</u>

u = 3x

du = 3dx

<u>Step 3: Integrate</u>

  1. [Integral] Rewrite:                                                                                           \displaystyle \frac{1}{3}\int {3sin(3x)} \, dx
  2. [Integral] U-Substitution:                                                                                \displaystyle \frac{1}{3}\int {sin(u)} \, du
  3. [Integral] Trig Integration:                                                                              \displaystyle \frac{1}{3}[-cos(u)] + C
  4. [Expression] Multiply:                                                                                     \displaystyle \frac{-cos(u)}{3} + C
  5. [Expression] Back-Substitute:                                                                        \displaystyle \frac{-cos(3x)}{3} + C
