pi / | | sin(x) | e *cos(x) dx | / pi -- 2
Integral(E^sin(x)*cos(x), (x, pi/2, pi))
Let .
Then let and substitute :
The integral of a constant is the constant times the variable of integration:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | | sin(x) sin(x) | e *cos(x) dx = C + e | /
Use the examples entering the upper and lower limits of integration.
