Arteries carry blood away from the heart, whereas veins carry blood back towards the heart.Arteries have much thicker muscular walls in comparison to veins, as they need to carry blood at hi...

f(x) = 6x²+2x+1, f'(x)= [f(x+h)-f(x)]/h here is the original equation and the formula used to differentiate from first principles. For this proof the limit of h is: h=0 and should be stated thr...

For differentiation, we can follow a simple method for differentiating y with respect to x. It may be the case that you have special numbers such as e^x you need to differentiate and integrate b...

First sketch the line and the curve on the same axes (I would show this using the whiteboard).Then we want to find the points of intersection so set the two equations equal to each other and rearrange to ...

Geographic isolation occurs so the population is separated and the two groups cannot interbreed. Variation due to mutation arises in the separate populations leading to different alleles becoming dominant...
