1
Q
does the MVT apply to |x - 3| on [0, 5]
A
no, not differentiable at x = 3
2
Q
MVT
A
if f(x) is continuous and differentiable on the interval, then f’(x) = f(b)-f(a)/b-a
3
Q
does the MVT apply to sin(3x) on (0, pi)
A
no, because the interval is not closed
4
Q

A
a + i∆x
6
Q

A
2sinxcosx
7
Q
cos2x = ?
A
1 - 2sin^2x
2cos^2x - 1
8
Q
tan^2x = ?
A
sec^2x - 1
9
Q
t/f: distance can equal -9/4
A
false, distance must be positive
10
Q
to find the displacement function from the velocity function…
A
take the antiderivative
