tangent of 2xe^x

tangent of

2 x e^{x}

y = 2 (e^{a_{0}} + e^{a_{0}} a_{0}) x - 2 a_{0}^{2} e^{a_{0}}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 2 a_{0} e^{a_{0}})

Find the slope of

y = 2 x e^{x} : \frac{d y}{d x} = 2 (e^{x} + e^{x} x)

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = 2 (e^{a_{0}} + e^{a_{0}} a_{0})

Find the line with slope m=

2 (e^{a_{0}} + e^{a_{0}} a_{0})

and passing through

(a_{0}, 2 a_{0} e^{a_{0}}) : y = 2 (e^{a_{0}} + e^{a_{0}} a_{0}) x - 2 a_{0}^{2} e^{a_{0}}

y = 2 (e^{a_{0}} + e^{a_{0}} a_{0}) x - 2 a_{0}^{2} e^{a_{0}}
