Integral(sin(x/2), (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:
/ | | /x\ /x\ | sin|-| dx = C - 2*cos|-| | \2/ \2/ | /
2 - 2*cos(1/2)
=
2 - 2*cos(1/2)
Use the examples entering the upper and lower limits of integration.
