use chain rule and
what i know is, if i had to find then i would go about:
plugging values gives
similarly can find [/tex] u_\theta , v_r and v_theta[/tex]
but to find , how would i set up the chain rule to begin with? In above case, x and y are function of r and theta so it makes sense. ho.wever, here i can't do similar with u_x...i think.
please show full work if possible.
