\(\displaystyle (\dfrac{\pi }{4})[[4 \sin \dfrac{\pi}{4}] + [4 \sin \dfrac{\pi }{2}] + [4 \sin \dfrac{3\pi }{4}] + [4 \sin \pi] + [4 \sin \dfrac{5\pi }{4}] + [4 \sin \dfrac{3\pi }{2}]]\) What does this come out to?
My attempt:
\(\displaystyle (\dfrac{\pi }{4})[[4 (.707106781)] + [4 (1)] + [4(.70710678118)] + [4 (0)] + [4 (-.7071067811)] + [4(-1)]]\)
My attempt:
\(\displaystyle (\dfrac{\pi }{4})[[4 (.707106781)] + [4 (1)] + [4(.70710678118)] + [4 (0)] + [4 (-.7071067811)] + [4(-1)]]\)
