Homework Help: math

Posted by r. giggs on Saturday, May 12, 2007 at 3:17am.

could somebody tell me the answer or order of operations to this calculation.

3cos(2 x 2)

thanks.

I assume you meant

3cos(2x²)

pick your x
square it
multiply it by 2
take its cosine
multiply by 3

press the = sign on your calculator after each step to overwrite any build-in order of operation
