thanks for any insight

equations:

x*cos((2*pi*50*z)/2000)) - y*sin((2*pi*50*z)/2000))=.008

x*cos((2*pi*60*z)/2000)) - y*sin((2*pi*60*z)/2000))=.009

x*cos((2*pi*70*z)/2000)) - y*sin((2*pi*70*z)/2000))=.006

x*cos((2*pi*80*z)/2000)) - y*sin((2*pi*80*z)/2000))=.005

x*cos((2*pi*90*z)/2000)) - y*sin((2*pi*90*z)/2000))=.0009

x*cos((2*pi*100*z)/2000)) - y*sin((2*pi*100*z)/2000))=.0008

x*cos((2*pi*110*z)/2000)) - y*sin((2*pi*110*z)/2000))=.0001
