回答:

#R =(costheta-5sintheta)/(SIN(的2θ))#

说明:

为此,我们将使用两个方程式:

#X = rcostheta#

#,Y = rsintheta#

#5rsintheta = rcostheta-2(rcos theta)(rsintheta)#

#5rsintheta = rcostheta-2R ^ 2costhetasintheta#

#5sintheta = costheta-2rcosthetasintheta#

#2rcosthetasintheta = costheta-5sintheta#

#R =(costheta-5sintheta)/(2costhetasintheta)#

#R =(costheta-5sintheta)/(SIN(的2θ))#
