The perfect tense is used to for completed actions in the past. For example, le semaine dernier je suis allé en France would translate to last week I went to France. The imperfect is used for incomplete acti...

e (x ^2+2) =f(x)=y Is the equation we will use to demonstrate correct use of the chain rule. The equation at the core of the chain rule is: dy/dx=dt/dx*dy/dt Seeing that dt as a numerator and dt as a denomin...

Effective Nuclear Charge is the net positive nuclear charge experienced by a valence electron orbiting the positively charged nucleus in an atom. Effective nuclear charge is redcued by: -increased distance b...

First differentiate the function: y = f(x) => dy/dx = f'(x) Then set dy/dx = 0 and find the solutions. i.e. solve 0 = f'(x) For each value of x that is a solution, substitute back into f(x) to get the y c...
