Hi,

I work with Excel on this math report and the formula I typed in just kept
not working properly. The results were all off. So I checked everything very
carefully and found out why it didn't work. In need to calculate sin and cos
so I typed =SIN(45) in one cell and =COS(45) in another cell just to check if
it works and ... Surprise! I ended up with two different results instead of
0,707 for both!!! I tried with =SIN(0), =SIN(180) and =SIN(360) and again ...
wrong (supposed to be "0" for all of them). If someone knows a way to fix
that, it would be of great help!

By the way, Happy Valentine Day!

The trig functions use radians, not degrees. Try =SIN(45*PI()/180).

Excel uses radians--not degrees:

=SIN(RADIANS(45))
or
=SIN(45*PI()/180)

In Excel, angles should be expressed in Radians, not degrees

=SIN(RADIANS(45))-COS(RADIANS(45)) returns (almost) zero

*Knocks her head on the table*

I COMPLETLY forgot about radian and worst of all I knew it!!! *sigh* So much
time wasted on something as easy as that... what a shame!!! lol

Thanks to all of you guys!
