Expert Answer
Given: x=acos3theta and y=bsin3theta
dx over dθ equals negative 3 acos squared straight theta space sinθ
dy over dθ equals 3 bsin squared straight theta space cosθ
dy over dx equals negative bsinθ over acosθ equals negative straight b over straight a tanθ
fraction numerator straight d squared straight y over denominator dx squared end fraction equals negative straight b over straight a cross times straight d over dθ open parentheses tanθ close parentheses cross times dθ over dx equals negative straight b over straight a cross times fraction numerator sec squared straight theta over denominator negative 3 acos squared straight theta space sinθ end fraction equals fraction numerator bsec to the power of 4 straight theta over denominator 3 straight a squared sinθ end fraction
