3 / | | 3*sin(3*x - 6) dx | / 1
Integral(3*sin(3*x - 6), (x, 1, 3))
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 sine is negative cosine:
So, the result is:
Now substitute back in:
So, the result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 3*sin(3*x - 6) dx = C - cos(3*x - 6) | /
