👉 In mathematics, a derivative is a function that gives the instantaneous rate of change of a function with respect to one of its variables. It is denoted by "dy/dx", and it represents how much the value of the dependent variable changes for every unit increase in the value of the independent variable. For example, consider a function f(x) = x^2 - 5x + 6. The derivative of this function with respect to x would be: f'(x) = d
