\(\displaystyle (\dfrac{\pi }{8})[[4 \cos \dfrac{\pi }{8}] + [4 \cos \dfrac{\pi }{4}] + [4 \cos \dfrac{3\pi }{8}]] + [4 \cos \dfrac{\pi }{2}]\) What does this come out to?
My attempt:
\(\displaystyle (\dfrac{\pi }{8})[[4 (.9238795325)] + [4(.70710678118)] + [4(.38268343236)] + [4(0)]]\)
My attempt:
\(\displaystyle (\dfrac{\pi }{8})[[4 (.9238795325)] + [4(.70710678118)] + [4(.38268343236)] + [4(0)]]\)
