Do you mean how to setup the integral?
or how to actually integrate it?
I'm trying to show the calculation of the area under the graph of semicircle f(x) = - (4-x^2)^1/2 from [-2,2] by integration.
I understand the calculation can be done by taking antiderivative F(2) - F (-2), but I can't remember how to find F for this type.
Thanks!
