is this proof valid? I thought it out myself with some help from textbooks?

Can you explain to be the part on the bottom when we set g2=g(x+h) but E(g2) turns into E(g(x)) not E(g(x+h)) ? If that's valid, why is the limit as h approaches 0 of E(g(x)) is 0 ?

Is it correct...I suspect there maybe some circular reasoning with the "error term" becoming 0 as h approaches 0.

It's from a textbook...I just re-typed it into a word doc...

Is this proof of the chain rule valid ?

Does Snell's law apply in refraction when the light ray is along the normal line? Utilizing snell's law, the index of refraction (n) would be zero. nr= ni(sin θi)/sinθr Sin(θi)= 0 therefore, nr=0 However,utilizing the formula for index of refraction (n=c/v), the index of refraction...
