1) Integrate the following functions: f(x)=cos(3x)
Question
- Integrate the following functions: f(x)=cos(3x)
Solution
To integrate the function f(x) = cos(3x), you can use the formula for the integral of cosine, which is ∫cos(ax) dx = (1/a)sin(ax) + C, where a is a constant, x is the variable of integration, and C is the constant of integration.
Here, a = 3.
So, the integral of f(x) = cos(3x) is:
∫cos(3x) dx = (1/3)sin(3x) + C.
