Derivative of power function
Derivatives of Exponential Functions. we cannot use power rule as we require the exponent to be a fixed number and the base to be a variable. Instead, we're going to have to start with the definition of the derivative: \begin {aligned} f' (x) &= \lim_ {h \rightarrow 0} \dfrac {f (x + h) - f (x)} {h}\\ &= \lim_ {h \rightarrow 0} \dfrac {a^ {x ... WebFind the derivative of f (x) = e^x (x^2 + 1). f (x) = ex(x2 +1). Let u = e^x u = ex and v = x^2 + 1 v = x2 +1 so that f (x) = uv f (x) = uv. Then u' = e^x u′ = ex and v' = 2x. v′ = 2x. As f (x) = uv, f (x) = uv, we get that f' (x) = uv' + u'v, f ′(x) = uv′ +u′v, which implies
