## 3.2: The Derivative as a Function

The derivative formula is defined for a variable 'x' having an exponent 'n'. The exponent 'n' can be an integer or a rational fraction. Hence, the formula to calculate the derivative is: d dx.xn =

## Derivative Calculator • With Steps!

Put in f (x+Δx) and f (x): x2 + 2x Δx + (Δx)2 − x2 Δx. Simplify (x 2 and −x 2 cancel): 2x Δx + (Δx)2 Δx. Simplify more (divide through by Δx): = 2x + Δx. Then, as Δx heads towards 0 we get: = 2x. Result: the derivative of x2 is 2x. In other

## How do users think about us Actually it's really a smart app, even though u have to pay for the premium, you don't really have to because you can always wait for the ads, and know the steps of ur answer, like let's be honest its free, waiting isn't a big deal for me, so I would highly recommend this app, you'll like have to wait 2 to 5 minutes to get ads, but it's worth it because all the answers are correct.
