Hello, Jhevon,

I've attached an image of the calculations to b) and c). Part a) needs some more typing but I hope I can post my considerations to a) pretty soon:

Based on how earboth did parts b) and c), here's how i think a) should be done. Am i correct?

Hi, Jhevon,

it's me again.

I did a) in a different way than you did (to be exact you should use probably absolute values)

would i have to state i am approximating cos(x) with a/b. since there are values for cos(x) that are irrational and can't be written as a rational function

In his example, earboth stated that a and b are elements of irrational numbers.

Ah yes, he said they are from the reals, which includes the irrationals. ok, thanks
