Evaluate {eq}\int_0^{\pi/2} (2-\sin\theta)^2 \ d\theta {/eq}
Question:
Evaluate {eq}\int_0^{\pi/2} (2-\sin\theta)^2 \ d\theta {/eq}
Evaluate the Integral:
Let us assume that {eq}f(x) {/eq} is the function of {eq}x {/eq} and we want to find a integral of {eq}f(x) . {/eq} To find this integral we need to find the anti-derivative of {eq}f(x) {/eq} with respect to {eq}x {/eq} using the following integral formula.
{eq}\displaystyle\int \cos \left(u\right)du=\sin \left(u\right)\\ \displaystyle\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1 {/eq}
