Q
The left derivative of f at point x
A
(The one to the right of ‘and’)
20
Q
Quotient rule
A
Where f and g are differentiable functions
21
Q
Corollary to Fermat’s theorem? Give example
A
F does not have to be differentiable at the point where it has a local extremum.
Eg:
f(x) = |x| attains (global) min at x=0
But f’(0) doesn’t exist

Q
Taylor expansion of sin(x)
A
24
Q
Taylor expansion of cos(x)
A
25
Taylor expansion of log(1+x)
26
Asymptotic expansion of f, a function defined in a neighbourhood of x_0 €**R**
27
Asymptotic expansion of (below) as x -> 0
28
Compute first 3 non trivial terms of Taylor expansion
29
Requirements for Taylor’s formula to be valid
f€cn(a,b) and x_0 must be in (a,b)
