This one looks pretty easy, but I keep getting the wrong answer. Here's the problem.
−
<math>\int_{0}^{2Pi}\sqrt{\frac{1-\cos{x}}{2}}dx</math>
−
−
Obviously, <math>\frac{1-\cos{x}}{2} = \sin^2{\frac{x}{2}}</math>
−
−
So, the integral should then look like:
−
−
<math>\int_{0}^{2Pi}\sin{\frac{x}{2}}dx</math>
−
−
Integrated, it comes out to:
−
−
<math>[-2\cos{\frac{x}{2}}]_{0}^{2Pi}</math>
