I'm studying for a maths test.
I know that the second derivative of the position R(t) of a particle moving in the plane, in polar coordinates, is (r''-r([tex]\vartheta[/tex]')2)er + (r[tex]\vartheta[/tex]''+2r'[tex]\vartheta[/tex]')eo. o = [tex]\vartheta[/tex]
How to differentiate this to find R'''(t), in polar coordinates and in turn find R'''(1) in polar coordinates if R(t) has polar coordinates r(t) = t2, [tex]\vartheta[/tex](t) = t2
