pi -- 2 / | | (4*sin(x) + 2*cos(x)) dx | / 0
Integral(4*sin(x) + 2*cos(x), (x, 0, pi/2))
Integrate term-by-term:
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:
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:
The result is:
Add the constant of integration:
The answer is:
/ | | (4*sin(x) + 2*cos(x)) dx = C - 4*cos(x) + 2*sin(x) | /
