Square root of negative 21
WebUsing this argument we have seen that the square root of a negative number cannot be positive or negative. (We also know it can't be 0, since 0 × 0 = 0 which isn't negative either) Later your will learn that defining a special object i: = √− 1, will let you take the square root of a negative number. Share. WebThe sqrt function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbers z = u + i*w, the complex square root sqrt (z) returns sqrt (r)* (cos (phi/2) + 1i*sin (phi/2))
