1 / | | cos(4*x) dx | / 0
Integral(cos(4*x), (x, 0, 1))
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:
Add the constant of integration:
The answer is:
/ | sin(4*x) | cos(4*x) dx = C + -------- | 4 /
sin(4) ------ 4
=
sin(4) ------ 4
sin(4)/4
