x - 2 / | | 2*cos(x) dx | / 0
Integral(2*cos(x), (x, 0, x/2))
The integral of a constant times a function is the constant times the integral of the function:
The integral of cosine is sine:
So, the result is:
Add the constant of integration:
The answer is:
/ | | 2*cos(x) dx = C + 2*sin(x) | /
/x\ 2*sin|-| \2/
=
/x\ 2*sin|-| \2/
2*sin(x/2)
