Hi all,

New to SDN here. Well, not really new since I've been reading the forums for months but I just registered and this is my first post.

Anyway, I've been going through TBR's physics book and the very last example of the first section (translational motion) makes use of the quadratic formula. For those of you who have taken the MCAT, or for those of you who are well-versed on the beast, is this a necessary formula to memorize and know?

you don't need to know it at all.


pwned.

That's how I memorized it back in 8th grade and I still remember it.

I think they show the equation so that they can show an alternative solution. It emphasizes the point that while in school you had to use the quadratic equation, but you should not use it on the MCAT. I think the point of that was to show you how much better POE (process of elimination) works compared to what they made us do on a real physics exam. They do this a few times in the chapters I've been through, but it's been so long since I've had physics, I don't really remember the way I was supposed to solve it. I also had a pretty crappy eight grade math teacher I suppose, because we didn't get any lyrical instruction.

you dont need to know it...and on the real mcat it is highly unlikely that you will have to do that much math to figure out the answer
