Calculate Pi with Python - GeeksforGeeks
WebSep 6, 2015 · Explanation: Using a unit circle in standard position, the angle ( −π) is a semicircle with its terminal point on the negative X-axis (at (x,y) = − 1,0) The length of the hypotenuse will be. XXX√( − 1)2 +02 = 1. and since the definition of sec is. XXXsec = hypotenuse x-coordinate (of unit circle) sec( − π) = 1 −1 = −1. Answer link.
