Give an example of a function F(x) that is an antiderivative of f(x) = 9 cos(9x)+ 3x^2

liubo4ka [24]

We are integrating f(x) = 9cos(9x) + 3x²: $\int\ {9cos(9x)+3x^{2} } \, dx$

a) Apply the sum rule

$\int\9cos(9x)} \, dx +\int\ 3x^{2} } \, dx$

b) Calculate each antiderivative

<u>First integral</u>

$\int\ {9cos(9x)} \, dx$

1. Take out the constant

$9\int\ {cos(9x)} \, dx$

2. Apply u-substitution, where u is 9x

$9\int\ {cos(u)\frac{1}{9} } du$

3. Take out the constant (again)

$9*\frac{1}{9} \int{cos(u)} du$

4. Take the common integral of cos, which is sin

$9*\frac{1}{9}sin(u)}$

5. Substitute the original function back in for u and simplify $9*\frac{1}{9} sin(9x) = sin(9x)$

6. Always remember to add an arbitrary constant, C, at the end

$sin(9x) + C$

<u>Second integral</u>

$\int3x^{2} } \, dx$

1. Take out the constant

$3\int{x^{2} } \, dx$

2. Apply the power rule, $\int{x}^{a} \, dx =\frac{x^{a+1} }{a+1}$ , where <em>a</em> is your exponent

⇒ $3*\frac{x^{2+1} }{2+1} = x^{3}$

3. Add the arbitrary constant

$x^{3} + C$

c) Add the integrals

sin(9x) + C + x³ + C = sin(9x) + x³ + C

Notice the two arbitrary constants. Since we do not know what either constant is, we can combine them into one arbitrary constant.

<h3>Answer:</h3>

F(x) = sin(9x) + x³ + C
