回答:
#r = sintheta /(2sin ^ 2theta + 3cos ^ 2theta-sin(2theta))#
説明:
このために我々は必要となるでしょう:
#x = rcostheta#
#y = rsintheta#
#rsintheta = 2(rsintheta)^ 2 + 3(rcostheta)^ 2-2(rcostheta)(rsintheta)#
#rsintheta = 2r ^ 2sin ^ 2theta + 3r ^ 2cos ^ 2theta-2r ^ 2costhetasintheta#
#sintheta = 2rsin ^ 2theta + 3rcos ^ 2theta-2rcosthetasintheta#
#sintheta = 2rsin ^ 2theta + 3rcos ^ 2theta-rsin(2theta)#
#シンテータ= r(2sin ^2θ+ 3cos ^2θ-sin(2θ))#
#r = sintheta /(2sin ^ 2theta + 3cos ^ 2theta-sin(2theta))#
