Symbolically this is the limit of fc-fchh as h0. Google Classroom Facebook Twitter. In other words the slope at x is 2x.
With the limit being the limit for h goes to 0.
Derivatives can be generalized to functions of several real variables. The inverse operation for differentiation is known as In this topic we will discuss the derivative formula with examples. 2x Dx. For this reason the derivative is often described as the instantaneous rate of change the ratio of the instantaneous change in the dependent variable to that of the independent variable.
