Q

What is the product rule?

17
Q

What are the answers to this equation?
Why?

A

Because e^x has an asymptote when x=0 so there are no solutions

26
How do you prove that:
27
How do you prove that:
28
How do you prove that the derivative of sinx is cosx?
Small angle approximations
29
What is the quotient rule?
30
How do you do parametric differentiation?
31
How do you do implicit differentiation?
Differentiate each term normally, if there is a y term then you write dy/dx after it Rearrange to find dy/dx
32
What do i always forget to do with implicit differentiation?
Differentiate the constant on the other side of the equal sign down to 0
33
34
What do I always forget to do when differentiating cos^2x?
Have the negative sign
35
What is a point of inflection?
When the curve changes from convex to concave
36
When is there a maximum point?
f''(x)<0 Concave
37
When is there a minimum point?
f''(x)>0 Convex
