Hi I have solved two equations and now I would like to calculate/simplify the results, before I turn them from rad's to deg's. But somehow I wont allow me to. My code (so far) looks like this:
syms x
eta = ((30+42)/2)*(pi/180);
gamma = 2*pi/3;
X = solve(1*cos(gamma-eta)-1.2*cos(x-eta),x)
Y = solve(1*sin(gamma-eta)-1.2*sin(x-eta),x)
My results then become
X =
pi/5 + acos(12553449285915085/144115188075855872)
pi/5 - acos(12553449285915085/144115188075855872)
Y =
pi/5 + asin(22394642186961775/27021597764222976)
(6*pi)/5 - asin(22394642186961775/27021597764222976)
what I would like to do is simmelar to
>> pi/5 + acos(12553449285915085/144115188075855872)
ans =
2.1119
>> radtodeg(ans)
ans =
121.0028
But this I can only do from the command window, How do I do this from my code?

The obvious suggestion is for you to post the relevant parts of your script ‘.m’ file.
What errors or unexpected results do you get when those commands are part of your script file?

Mikkel, use
X = vpa(solve(1*cos(gamma-eta)-1.2*cos(x-eta),x))
Y = vpa(solve(1*sin(gamma-eta)-1.2*sin(x-eta),x))
instead.
