What is R?

By Quadradic Forumula,

x=[(-1)+/-isqrt(3)]/2

Let us say that,

R=(-1/2)+(sqrt(3)/2)i

The "-" should give the same result.

Now express in polar coordinates,

cos(5pi/6)+i*sin(5pi/6)

Now you can easily compute what 3333,333,33,3

Given when raised to their power through de-Moiver's theorem.

Use paranthesis!2) What is the domain of the 1-to-1 function f(x)= 2^x/2 - 3; find the inverse function and its range. Then, show that the composite functions f(f^1(x)) and f^1(f(x)) are both equal to x.
