d2y/dx2 for parametric equations

[eks129]

can i do second derivatives on the calc?

or if anyone knows how to do it by hand, please let me know. my calc teacher is an awful help (literally) and the equation in my book is absurd.

thank you!

You can do the second derivative, or any other level for that matter.

For the purposes of the following function "d" is written using [2nd] + [8].

Type in:
d(the equation such x^3, the variable you are using most often just x, the level of the derivative you want in your case 2)

The last argument is optional, and the default of it is to just take the first derivative.

Example then:
d(x^3-4,x,2)

would return:
6x
