The results your program and your calculator
are giving you are correct! The thing is your
program is giving you the answer in RADIANS
and your calculator in DEGREES.
If you did maths at a high level at
school then you should know the difference
To convert radians to degrees you would
use: theta*(pi/180)
so you would just change your function to:
result = sin(theta*(pi/180));
Apart from that I can't help you. There may
be somthing that changes the mode or a
seperate function for getting the sine of
theta in degrees?

----------
for instance here's the output from a simple prog I did to test my idea

Sin of 0 is 0.000000
Sin of 1 is 0.841471
Sin of 2 is 0.909297		; RADIANS
Sin of 3 is 0.141120
Sin of 4 is -0.756802

But using a calculator I get

Sin of 0 is 0
Sin of 1 is 0.017452
Sin of 2 is 0.034899		; DEGREES
Sin of 3 is 0.052335
Sin of 4 is 0.069756
