Question

for the curve y=4x^3 -3x^5 find all the points at which tangent passes through the origin

Answer 1

can any one ans this question

Answer 2

i am not able to understand

Answer 3

can u explain me???????

Answer 4

at a tangent to a any curve the derevative at that point is zero so d/dx=0,then u take the x value and subtitute them at the equation y=4x^3-3x^5.

Answer 5

but then everything becomes zero

Answer 6

but there are more than 1 point , how to identify the other

Answer 7

thnx

Answer 8

if you want the tangent line to pass through the origin then the answers are

\[\pm\frac{\sqrt{6}}{3},0\]

Answer 9

that is \[x=\pm\frac{\sqrt{6}}{3},0\]
