Find all critical numbers of the function f(theta)=4theta-tan(theta), that
lie in the interval [0, 2pi].
2.
A particle is moving along the curve y=5sqrt(4x+5). As the particle passes through the
point(1,15) , its x-coordinate increases at a rate of 3 units per second. Find the
rate of change of the distance from the particle to the origin at this
instant.
