1 / | | (1 + cos(6*x)) dx | / 0
Integral(1 + cos(6*x), (x, 0, 1))
Integrate term-by-term:
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:
The integral of a constant is the constant times the variable of integration:
The result is:
Add the constant of integration:
The answer is:
/ | sin(6*x) | (1 + cos(6*x)) dx = C + x + -------- | 6 /
sin(6) 1 + ------ 6
=
sin(6) 1 + ------ 6
