tangent of x^3-2x+2,\at x=3,y=21

tangent of

x^{3} - 2 x + 2, at x = 3, y = 21

y = 25 x - 52

Solution steps

Find the tangent point:

(3, 23)

Find the slope of

y = x^{3} - 2 x + 2 : \frac{d y}{d x} = 3 x^{2} - 2

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 = 25

Find the line with slope m=

25

and passing through

(3, 23) : y = 25 x - 52

y = 25 x - 52

\frac{\partial}{\partial x} (\frac{8 x + 5 y}{z})

\frac{\partial}{\partial x} (2 (\frac{y}{x})^{0.5})

- \frac{y}{( x ^{2} + y ^{2} )} d x + \frac{x}{x ^{2} + y ^{2}} d y = 0

\int (x - 1) (x - 4) d x

\int \frac{22}{x 1 + 2 x} d x
