it should be 0.707
and sind(18)=-0.9511

Theres 2 things that could be wrong.
1. User error - You're actually putting in something like: (-90 + 18) and (-90 + 45), instead of 18 and 45. - This is what I expect
2. A bad prank - Someone has written a function called sind that doesn't do what you think it should, and you're actually using that function.

If the result of:
which sind
says built-in, then you're using the built in version. If it says ....\sind.m, then the file can have been altered (which would be a bad prank)
