Homework Statement
[tex]\int _{0}^{2\,\pi}\!\int _{0}^{1}\! 0.5\,{r}^{ 3.5}\sin \left( \theta
\right) {\cos}^{2}+ 0.5\,{r}^{ 2.5}{\sin}^{2}+1/5\,{r}^{5}{\cos}^{2}{
dr}\,{d\theta}[/tex]
Homework Equations
The Attempt at a Solution
So I first integrate the r, which was relatively straight forward, the tricky part was the theta, I had to use the double angle formula? then evaluating, which for the end answer, I got
[tex]\frac{39}{20}\Pi-\frac{3}{4}[/tex]
which looks kinda wrong to me...
tips and hints appreciated
