Gratuitously Polarized

Calculus Level 3

x = r cos ( θ ) y = r sin ( θ ) r = sec ( θ ) for 0 θ π 4 r = csc ( θ ) for π 4 < θ π 2 \begin{array} {cc} x = r \cos (\theta) \\ y=r \sin(\theta) \\ r = \sec(\theta) & \text{for } 0 \leq \theta \leq \frac{\pi}{4} \\ r = \csc(\theta)& \text{for } \frac{\pi}{4} < \theta \leq \frac{\pi}{2} \end{array}

The curve described above exists within the x y xy plane. Determine the area bounded by this curve, the x x -axis, and the y y -axis.


The answer is 1.

Gratuitously, indeed. It's an unit square!

Well said xD
