1 / | | sin(4*x - 1) dx | / 0
Integral(sin(4*x - 1), (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 sine is negative cosine:
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | cos(4*x - 1) | sin(4*x - 1) dx = C - ------------ | 4 /
cos(3) cos(1) - ------ + ------ 4 4
=
cos(3) cos(1) - ------ + ------ 4 4
-cos(3)/4 + cos(1)/4
Use the examples entering the upper and lower limits of integration.
