Math Problem Statement

Explain how and why you got the numbers and where they come from for all of the steps.

Explain how and why you got the numbers and where they come from for all of the steps.

Solution

Let's work through each problem and find the anti-derivatives, step-by-step. I'll explain the reasoning and calculations behind each step.


Problem 1:

(4x2+4x+9)dx\int (4x^2 + 4x + 9) \, dx For each term in the integrand:

  1. 4x2dx=43x3\int 4x^2 \, dx = \frac{4}{3} x^3 since the power rule states xndx=xn+1n+1\int x^n \, dx = \frac{x^{n+1}}{n+1}.
  2. 4xdx=2x2\int 4x \, dx = 2x^2, applying the power rule.
  3. 9dx=9x\int 9 \, dx = 9x, since the integral of a constant is the constant times xx.

Putting it together: (4x2+4x+9)dx=43x3+2x2+9x+C\int (4x^2 + 4x + 9) \, dx = \frac{4}{3} x^3 + 2x^2 + 9x + C


Problem 2:

(5w7ew+6w3)dw\int \left( \frac{5}{w} - 7e^w + 6\sqrt[3]{w} \right) \, dw

  1. 5wdw=5lnw\int \frac{5}{w} \, dw = 5 \ln |w|, since 1wdw=lnw\int \frac{1}{w} \, dw = \ln |w|.
  2. 7ewdw=7ew\int -7e^w \, dw = -7e^w, as the integral of ewe^w is ewe^w.
  3. ( \int 6w^{1/3} , dw = \frac{6}{4/3} w^{4/3} = \frac{18}{2} w^{4/3}
