[微積] 求兩題做法與解
1.
A particle is moving along the curve y=5sqrt(4x+5) . As the particle passes
through point (1,15) , its x-coordinate increases at a rate of 3 units per second.
Find rate of change of the distance from the particle to the origin at this
instant.
2.
Find all critical numbers of the function f(θ)=4θ-tan(θ) , that lie in the interval [0,2pi] .
