p - 6 / | | (1 - cos(6*x)) dx | / p - 4
Integral(1 - cos(6*x), (x, p/4, p/6))
Integrate term-by-term:
The integral of a constant is the constant times the variable of integration:
The integral of a constant times a function is the constant times the integral of the function:
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of cosine is sine:
So, the result is:
Now substitute back in:
So, the result is:
The result is:
Add the constant of integration:
The answer is:
/ | sin(6*x) | (1 - cos(6*x)) dx = C + x - -------- | 6 /
/3*p\ sin|---| sin(p) p \ 2 / - ------ - -- + -------- 6 12 6
=
/3*p\ sin|---| sin(p) p \ 2 / - ------ - -- + -------- 6 12 6
