My proff mentioned something about proportionality: "To make an a proportionality into an equality, we must introduce a constant" Something along those words: my question is why? Can show prove this to me??

thanks but still not quite sure how you arrived at the answer

60 deg is right, but would you mind explaining it to me in a simpley way? or maybe introduce radians because we just skimmed over that section.

Highschool... I have a lot of extracurricular activities, like after school stuff but never mind that. Can you explain what calculus is because the wiki version isn't that friendly.

Doesn't the light refract in the rare medium meaning the angle of refraction is in the air?

I'm planning to go into medical field, so I'm thinking a science major right? Right now I am in year 3 high school. Math isn't my greatest but I must say I'm decent but in science(I've only take chem 11) I think I'm above average. Now year 4 is quite near (after this summer) and these are my...

Makes sense, but that "1" still exists in the fraction if (2^5)(3^4)/1. But I see how it is sort of irrelevant. Thank you, now what if the number was not in a fraction and was just simply; (7^-3) will this be correct? 1/(7^3)

Recently in class (11 math) we explored exponents in negatives. My teacher placed a question on the board and it said 7*1/7^-7 ( 7 times 1 over 7 to the power of -7 ) She said that in order to get rid of a negative, we must imagine that there is an imaginary "1" multipliying the fraction...

Thanks Doc
