How come Excel can't calculate any =SIN(x) or =COS(y) correctly?
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! |
