1 / | | 8*cos(4*x - 12) dx | / 0
Integral(8*cos(4*x - 12), (x, 0, 1))
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:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 8*cos(4*x - 12) dx = C + 2*sin(4*x - 12) | /
-2*sin(8) + 2*sin(12)
=
-2*sin(8) + 2*sin(12)
-2*sin(8) + 2*sin(12)
