So changing the above link to degrees would give x: 0, y: -90, z: 0. Unfortunately i copied the question as is so i may need to seek further clarification. The next 2 related questions are Next bit is to fill the gaps: The rotation matrix represents A rotation of _________ degrees about the...

Yes I get some understanding on this now. Thanks for your help. Side question, I don't suppose you know what each letter in the answer above represents on a graph so I know for next time and can visualise what is going on? Thanks again

I'm now going for x = exp(-b t) sin(a t) ??

How about, something like

General point is what's written on my paper. So i assume the answer would be x: 0, y: -1.5707963, z: 0

Hmm may have confused myself but would it look like

Sorry not sure i fully understand what your asking me to do? I thought the result was on that link i provided or are you asking me to a particular area?

The red line is what was already on the sheet and the blue line is what i believe the graph would look like? Thanks

I think the answer is x = a sin(t)/b

The below matrix represents a rotation. 0 0 -1 0 1 0 1 0 0 Im trying to obtain the general point (x y z) when rotated by the above rotation matrix? So visited https://www.andre-gaschler.com/rotationconverter/ entered the above figures and not sure which entry would be x y z but assume it...

Hi, sorry i forgot to include the main text: Some weight is added to a spring. The spring is then extended and released. The extension of the spring oscillates with decreasing amplitude. Hope this helps?

Completely new to this and wondered if someone can explain what the correct equation of motion is if x is extension, t is time and a,b are constants x = b log (at) x = a t exp(-b t) x = exp(-b t) sin(a t) x = a sin(t)/b
