WebMar 29, 2024 · Explanation: Using: secx = 1 cosx. 1 sinx = cscx. cos(x −y) = cosxcosy +sinxsiny. Start: cscx = sec( π 2 − x) cscx = 1 cos(π 2 − x) cscx = 1 cos(π 2)cosx + sin(π 2) ⋅ sinx. WebBecause the circumference of a circle is 2πr.Using the unit circle definition this would mean the circumference is 2π(1) or simply 2π.So half a circle is π and a quarter circle, which would have angle of 90° is 2π/4 or simply π/2.You bring up a good point though about how it's a bit confusing, and Sal touches on that in this video about Tau over Pi.
