p - 3 / | | 2*sin(x) dx | / 0
Integral(2*sin(x), (x, 0, p/3))
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:
Add the constant of integration:
The answer is:
/ | | 2*sin(x) dx = C - 2*cos(x) | /
/p\ 2 - 2*cos|-| \3/
=
/p\ 2 - 2*cos|-| \3/
2 - 2*cos(p/3)
Use the examples entering the upper and lower limits of integration.
