How do I find the area inside the cardioid #r=1costheta#?What I did I converted the equation $x^2y^22ax=0$ to polar form $r=2acos\theta$ and $z=\frac{x^2y^2}{2a}$ to $z = \frac{r^2}{2a}$ thus got the double integral as $$\int_{\pi/2}^{\pi/2} \int_{0}^{2acos\theta}\frac{r^2}{2a}\cdot r\cdot dr\cdot d\theta$$ which I calculated to be $\frac{3\pi a^3}{4}$3x−x2 − x2 2!
