Question

find d^2y/dx^2 6x^2+3y^2=1

Answer 1

do you know what dy/dx of the function is?

Answer 2

would it be 12x+3ydy/dx=0

Answer 3

No, 12x + 6ydy/dx = 0

Answer 4

and then what do we do?

Answer 5

After get the answer above,you need to differentiate again.So,you will get the final answer.

Answer 6

\[6x^2 + 3y^2 = 1\]
you can interchange a bit to get the equation in terms of y.
\[y = \sqrt{(1-6x^2)/3}\]
just differentiate this equation twice in respect to x to obtain \[d^2y/dx^2\]
