Hi All

I'm new to the MathCAD system totally and could do with some useful hints and explinations....... sadly I have been staring at the sceen for hours and getting no where.

Question:

How can I determine the formula for the second derivative in its simplest form of the function from these parametric equations.

x = sin3t - cos 3t y = cos 3t + sin 3t

Evaluate the derivative at t=1

Many Thanks

Mike

Hi Valery

Many thanks for your response , I had managed to reach the first derivative, but was a little lost from then.

Thanks again

Hi Mike,

If you are new to Mathcad, you may benefit from some free short tutorials on a number of Mathcad topics that can be found on LearningExchange.

OK!

But for solving Mike Ruddle's task it is better to study not Mathcad but Mathematic
