tangent of y=x^4+2x-1,(1,2)

tangent of

y = x^{4} + 2 x - 1, (1, 2)

y = 6 x - 4

Solution steps

Find the slope of

y = x^{4} + 2 x - 1 : \frac{d y}{d x} = 4 x^{3} + 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 = 6

Find the line with slope m=

6

and passing through

(1, 2) : y = 6 x - 4

y = 6 x - 4

\frac{d}{d x} (x^{5} - 5^{x})

f (x) = e^{x} cos (x)

\frac{d}{d x} (\frac{40 + 24 x ^{4}}{1 + 4 x ^{4}})

\frac{x}{x + 6}

\int \frac{x ^{2} - 1}{x ( x + 1 ) ^{3}} d x
