My world falls apart when math isn't logical..

My calculator: cos(0)=1 cos(90)=1
Unity Engine: cos(0)=1 cos(90)=-0.4480736

Can someone explain to me why this is? All I want is a cosine is 90 to equal 0.. Thats all Ive ever really wanted.

 

Maybe you should convert to degrees, then, rather than using radians. By the way, cos(90) will never equal 1. I assume you used sin(90). Lesson: math is always logical.

Don't worry, you're not the first to be caught by the whole units thing http://www.wired.com/2010/11/1110mars-climate-observer-report/

You can see that Google agrees with Unity.

As a fan of mathematics, I have to agree. <3 radians

 

Damn in my post I said cos(90)=1, by bad, it equals 0.

 

Thanks for the support with Deg2Rad, Ill go try that out.
