Question

If x and y are connected parametrically by the equation given exercise without eliminating the parameter, Find dydx.
x=sin3tcos2t,y=cos3tcos2t

Open in App
Solution

dxdt=sin3tsin2tcos2t+cos2t(3)sin2tcostcos2t

dydt=cos3tsin2tcos2t+cos2t(3)cos2tsintcos2t

dydx=2sintcos4t+3cos2tcos2tsint2sin4tcost+3cos2tsin2tcost

dydx=2cos3t+3cos2tcost2sin3t+3cos2tsint
