tangent of x^4

tangent of

x^{4}

y = 4 a_{0}^{3} x - 3 a_{0}^{4}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, a_{0}^{4})

Find the slope of

y = x^{4} : \frac{d y}{d x} = 4 x^{3}

Compute the slope of

y = x^{4}

x = a_{0} : m = 4 a_{0}^{3}

Find the line with slope m=

4 a_{0}^{3}

and passing through

(a_{0}, a_{0}^{4}) : y = 4 a_{0}^{3} x - 3 a_{0}^{4}

y = 4 a_{0}^{3} x - 3 a_{0}^{4}

f (x) = (3 x - x^{3}) (7 x + 6)

x \to 5 lim (\frac{1}{x ^{2}})

\int 2 x e^{2 x} d x

\int \frac{2 x - 1}{x + 1} d x

x \to 2 lim (\frac{3 x}{4 - x ^{2}})
