I have created three graphs: one tangent graph, one negative cotangent graph, and one circle.
Here is what I have so far:
%Functions
f1=@(theta1) tan(theta1)
f2=@(theta1) -cot(theta1)
t=linspace(0,2*pi);
x3=4*cos(t);
y3=4*sin(t);
%Plotting
g1=ezplot(f1,[-(5*pi)/2,(5*pi)/2])
hold on
g2=ezplot(f2,[-3*pi,3*pi])
hold on
plot(x3,y3)
grid on
I am supposed to find all intersections of the three graphs here, and that's where I am stuck. Thanks for any suggestions if you have any.
My output of the graph:
