Historically speaking, finding trig values and reciprocals were much much harder than pressing two buttons on a scientific calculator. So people wanted to have separate tables for looking up 1/sin x and so on. In fact, those weren't the only "extra" trig tables people had back then. Check out this fun ...

cis is a mathematical notation defined by cis x = cos x + i sin x, where cos is the cosine function, i is the imaginary unit and sin is the sine function. The notation is less commonly used in mathematics than Euler's formula, e , which offers an even shorter notation for cos x + i sin x, but cis(x) is widely used as a … See more The cis notation is a shorthand for the combination of functions on the right-hand side of Euler's formula: $${\displaystyle e^{ix}=\cos x+i\sin x,}$$ where i = −1. So, See more • De Moivre's formula • Euler's formula • Complex number See more Derivative $${\displaystyle {\frac {\mathrm {d} }{\mathrm {d} z}}\operatorname {cis} z=i\operatorname {cis} z=ie^{iz}}$$ Integral See more This notation was more common when typewriters were used to convey mathematical expressions. The cis notation is … See more Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2.
