Nope

I have calculated 10 times and got same result every time. 1.25 * x^3 - 2

If you are doing what you did before, then you have got the wrong method. This is parametric differentiation and needs to be done differently to how you did it before.

I know differentiation, but this parametric thing has lost me

 

[Jimlaad43]

You need to find d2y/dt2 and divide that by d2x/dt2.

I got 0.5, I fear I may be horribly wrong, I can't really describe my workings, because it was more trial and error

 

[Jimlaad43]

There should be some x's in there.

 

[Alexander Macdonald]

There should be some x's in there.

Then I'm horribly wrong

A little bit of Parametric Differentiation for you all.

 

[Sasha Jednak]

First time to see this kind of differentiation. Let's try another one.
10*t^3-2

 

[Ho3n3r]

Oh ****! Forgot about this

Anyway, cannot find where I found the problem, to post calculations, but the answer was 5:20 AM I remember. Sorry about that :/

 

[mystaaRS]

I was closest so in reality, I should ask the next question

 

[Jimlaad43]

As it's been up for a long time, I'll post the answer. It's 20(t^3)-4.
