How do you find the limit of $\frac{t^{2} - 4}{t^{3} - 8}$ $(t^2-4)/(t^3-8)$ as t approaches 2?
How do you write an equation points (3,2) and (3,5)?
An object is at rest at $(4, 5, 1)$ $(4 ,5 ,1 )$ and constantly accelerates at a rate of $\frac{5}{3} \frac{m}{s^{2}}$ $5/3 m/s^2$ as it moves to point B. If point B is at $(7, 5, 3)$ $(7 ,5 ,3 )$ , how long will it take for the object to reach point B? Assume that all coordinates are in meters.
Two objects have masses of $42 M G$ $42 MG$ and $48 M G$ $48 MG$ . How much does the gravitational potential energy between the objects change if the distance between them changes from $21 m$ $21 m$ to $15 m$ $15 m$ ?
A box with an initial speed of $4 \frac{m}{s}$ $4 m/s$ is moving up a ramp. The ramp has a kinetic friction coefficient of $\frac{5}{6}$ $5/6$ and an incline of $\frac{π}{3}$ $pi /3$ . How far along the ramp will the box go?
Question #fb12c
How do you find local maximum value of f using the first and second derivative tests: $f (x) = 4 x^{3} + 3 x^{2} - 6 x + 1$ $f(x) = 4x^3 + 3x^2 - 6x + 1$ ?

Question #f5014
How do you find the derivative of $f (x) = ln (2 x^{2} + 1)$ $f(x)=ln(2x^2+1)$ ?
