Im trying to place parameter values after I solved parametric eqn.
now Im using for loop and solving the eqn 360 times. is there any beter way to do so?
here is my code:
clear all,clc;
syms t2 t3 ;
a=30;b=60;c=50;d=70;
t3s=zeros(1,360);
for t1=1:1:360
eqns=[a*cosd(t1)+b*cosd(t2)+c*cosd(t3)==70,a*sind(t1)+b*sind(t2)+c*sind(t3)==0];
s=solve(eqns,t2,t3);
t3s(t1)=double(vpa(180+s.t3(2)));
%vpa(s.t2)
end

Maybe geometrical approach?
clc,clear
a = 30;
b = 60;
c = 50;
d = 70;
[t1,t2,t3] = meshgrid(0:20:360); % create 3D matrices for each variable
f1 = a*cosd(t1)+b*cosd(t2)+c*cosd(t3)-70;
f2 = a*sind(t1)+b*sind(t2)+c*sind(t3);
cla
p1 = isosurface(t1,t2,t3,f1,0); % first surface patch
p2 = isosurface(t1,t2,t3,f2,0); % second surface patch
patch(p1,'facecolor','r'); % display
patch(p2,'facecolor','b');
[~,fv] = SurfaceIntersection(p1,p2); % find intersection curves
patch('faces',fv.faces,...
'vertices',fv.vertices,...
'linewidth',2,...
'edgecolor','g')
axis vis3d equal
light

SurfaceIntersection function
