Reddit mentions of Single Variable Calculus: Early Transcendentals, 7th Edition

I saw this in the /r/physics thread and it appears that /u/Techercizer already gave you some sage advice. I'd like to add a point about your math, however...

>Algebraically, we could bring the speed of light to the opposite end of the equation... Square root of 186,282 miles per second is equal to something?

Where are you getting √c from? Drawing the m term away from c^2 and taking the square root of the other side leaves you with √(E/m) = c. By all means take more roots to your heart's content, but remember the first rule of solving equations: Whatever you do to one side of the equation you must do to the other. Come back when you understand the physical implications of taking √(√(E/m).

If I only possess vague, abstract conceptions of engineering concepts, can I really aid in the design of a suspension bridge? Can I do it without understanding calculus? I agree with Techercizer that your enthusiasm and curiosity are commendable, but when I hear you say things such as

>I don't feel that they are ignorant ramblings, rather concise logical statements

... from the other thread, you come off as not only ignorant, but arrogant as well.

Also, some reading! Check out this, this, and this. Enthusiasm and curiosity such as yours is rare, and deserves to be cultivated.

Check around for a used copy, I picked up a used copy of Stewart 7th edition at the beginning of this semester off amazon for ~30 bucks.

is this the single variable one you're referring to?
