Hi I have some vector function problems I'd like some help for, but I didn't see a forum for them so I'll start by posting one problem in case people don't know them.
I don't know all the english math terms so pardon me if the problem may seem like nonsense
I have a vector function, f(t)= (t^3-t, 3t+1).
I need to find all the cross points with the y-axis
All the points where the tangent is vertical
and all the tangents that are parallel with the line y=x
Thanks in advance and feel free to correct my math terms, be they wrong.
