Question 1061526: (x,y)=(рcos(θ)−ssin(θ),рsin(θ)+scos(θ))
Hey guys!I can't understand why x is equal to pcosθ−ssinθ and the same problem with y.
So could you explain me this in details if you know it?
There is a link to the problem https://i.stack.imgur.com/H1oe9.jpg
My teacher told me about Jacobian and transformation from catesian to polar system coordinates but no success.I also tried to solve it in polar coordinates and the same results/no success/

.
Based on what is shown in the Figure, I'd say (x,y) = (,).
Unfortunately, I don't know ( and you didn't provide it) what is "s".
If s = 0, then my formula coincides with the source.
