a problem on test 1
** **
On the test I have just taken for some reason my mind went blank a particular question. one of the problems I think you had 1.3cos^2(.15x)as the function. I thought it was a misprint because I tried to put cos^2 in my calculator and it kept saying error. So I assumed it was a misprint. I had a total brain fart, i know that it is [cos(.15x)^2], but it didn't occur to me til after taking the test. I am sure you take off for that, but just wanted to touch base with you about what the heck I was talking about. sorry about that, It wasn't one of my better days. thanks

No problem. If this affects your score seriously you could always take another Test 1.
However note that you shouldn't be relying on your calculator. When graphing a function you need to show how you have graphed it using transformations.
