1 / | | ________ | / 2 | x*\/ 4 - x dx | / 0
Integral(x*sqrt(4 - x^2), (x, 0, 1))
Rewrite the integrand:
SqrtQuadraticDenomRule(a=4, b=0, c=-1, coeffs=[-1, 0, 4, 0], context=(-x**3 + 4*x)/sqrt(4 - x**2), symbol=x)
Now simplify:
Add the constant of integration:
The answer is:
/ | | ________ ________ / 2\ | / 2 / 2 | 4 x | | x*\/ 4 - x dx = C + \/ 4 - x *|- - + --| | \ 3 3 / /
8 ___ - - \/ 3 3
=
8 ___ - - \/ 3 3
Use the examples entering the upper and lower limits of integration.
