I really need help on how to approach the problem. Does anyone know how to go about it or are there any examples like this one? Thank you so much!!!! the picture attached has the problem.
this is what I have this so far:
x= input('Please provide a radian:');
if cos(x)< 10^-20
disp('Invalid value.');
else
cos(x)>=10^-20;
tan(x)=abs(sin(x)/cos(x));
fprint('Tan(x) of the value is %f\n',tan(x));
end

I did receive an error message. I am stuck in how to get my program to do the conversion of degree and radian and I get an error for the tan equation

You can use the "d" versions so you don't need to convert and you can just enter the values directly in degrees: cosd(), sind(), tand(), atan2d(), etc.

Try this:
x= input('Please provide a radian: ');
if cos(x)< 10^-20
disp('Invalid value.');
else
tanx = abs(sin(x)/cos(x));
fprintf('Tan(x) of the value %f is %f\n', x, tanx);
end
