I am not to great in math as I have never really had a good teacher, But i don't blame it on the teacher. I was just recently in a calc 1 class and got a D and have to go back and retake it. Thogh I plan to do so, I still need to brush up my lower level math, such as pre-calc and algebra, trig. i was recommend on a few #math channels on IRC to take a pre-calc book and pick up a Schaum's Outline to try to get me in line in terms of math. I wanted to ask here if this is good advice and if so which Schaum's Outline should i get there seems to be quite a few in my ball park here. I havetaught myself alot of the stuff I have needed but it just hasent been enogh. such as in my pe-calc class we never saw any trig functions, so In calc 1 as well as physics 1 i had to get throgh it with never actually seeing a trig function before. All of my schools pre-calc classes are taught by TA's and my calc professor even recommended I not take it again.
