Integral of sin(3x+5) dx
The solution
Detail solution
-
Let u=3x+5.
Then let du=3dx and substitute 3du:
∫9sin(u)du
-
The integral of a constant times a function is the constant times the integral of the function:
∫3sin(u)du=3∫sin(u)du
-
The integral of sine is negative cosine:
∫sin(u)du=−cos(u)
So, the result is: −3cos(u)
Now substitute u back in:
−3cos(3x+5)
-
Now simplify:
−3cos(3x+5)
-
Add the constant of integration:
−3cos(3x+5)+constant
The answer is:
−3cos(3x+5)+constant
