Use a calculator to evaluate csc 3pi/14

We are asked to evaluate csc 3pi / 14. We first multiply 3 to pi. pi is a constant and equal to 3.1415. In this case, 3 pi is equal to 9.4248. We divide further the product by 14 equal to 0.6732. csc or cosecant is the inverse of sin. so we get first the sin of 0.6732 in radians equal to 0.6235. csc 3 pi/14 is equal to 1/0.6235 or 1.6.
