If I have a function y = if(x), where f(x) is a real valued function, would its derivative be y'=if'(x)...or does something different have to happen with the i part?
cheers,

The derivative of a complex number is the slope of the tangent line to the complex function at a given point. It measures the rate of change of the complex function with respect to the complex variable at that point.
The derivative of a complex number is calculated using the same rules as the derivative of a real-valued function. This includes using the power rule, product rule, quotient rule, and chain rule.
The derivative of a complex number is important in understanding the behavior of complex functions and their curves. It can also be used to find critical points, extrema, and inflection points of complex functions.
Yes, the derivative of a complex number can be a complex number. This occurs when the complex function has a non-zero imaginary component and the derivative has both a real and imaginary component.
One special case is when the complex function is analytic, meaning it can be represented by a power series. In this case, the derivative of the function is found by differentiating each term in the series. Another special case is when the complex function is a constant, in which case the derivative is equal to zero.
