Homework Statement
r''-(theta')^2=-g reads: second derivative of r minus the first derivative of theta squared equals negative g
2(r')theta'+(r)theta''=0 reads: 2 times the first derivative of r times the first derivative of theta plus r times the second derivative of theta.
both r and theta are a function of time. Oh and the derivatives of each variable are with respect to time.
