Introduction to Square Roots. Taking the square root of a number is the opposite of squaring the number. Even your calculator knows this because . x2. has above it. To find a square root, hit 2nd button , select , put the number in, close the parentheses and hit enter! Every positive number has two square roots: one positive and one negative ...

cSolve() or cZeros() can be used to find the roots of complex numbers. For example ³ i = cSolve(x³ = i, x) = cZeros(x³ - i, x) = {-i, - 3/2 + ½ i, 3/2 + ½ i} DeMoivre’s Theorem can be used to display and trace (i.e. read out) the roots of complex numbers.
