For t>0, a particle moves along the x-axis. The velocity of the particle at time t is given by
v(t)= 1+2sin((t^(2))/(2)).
The particle is at position x=2 at time t=4
At time t=4, is the particle speeding up or slowing down?
Slowing down, the acceleration and velocity are opposite signs.
How do you determine the concavity of a function?
Take the second derivative of the function, set the function equal to zero, and determine the points of inflection.
Derive
