An eigenvalue problem A certain kind of differential equation (see Section 7.9 ) leads to the root-finding problem tan \(\pi \lambda=\lambda\) where the roots \(\lambda\) are called eigenvalues. Find the first three positive eigenvalues of this problem.
A stone is thrown vertically upward with a velocity of \(30 \mathrm{m} / \mathrm{s}\) from the edge of a cliff \(200 \mathrm{m}\) above a river.Consider the following descriptions of the vertical motion of an object subject only to the acceleration due to gravity. Begin with the acceleration equation \(a(t)=v^{\prime}(t)=g,\) where \(g=-9.8 \mathrm{m} / \mathrm{s}^{2}\) a. Find the velocity of the object for all relevant times. b. Find the position of the object for all relevant times. c. Find the time when the object reaches its highest point. What is the height? d. Find the time when the object strikes the ground. A payload is released at an elevation of \(400 \mathrm{m}\) from a hot-air balloon that is rising at a rate of \(10 \mathrm{m} / \mathrm{s}\)
Find the solution of the following initial value problems. $$u^{\prime}(x)=\frac{e^{2 x}+4 e^{-x}}{e^{x}} ; u(\ln 2)=2$$
Locate the critical points of the following functions. Then use the Second Derivative Test to determine (if possible) whether they correspond to local maxima or local minima. $$f(x)=2 x^{2} \ln x-11 x^{2}$$
Find the solution of the following initial value problems. $$p^{\prime}(t)=10 e^{-t_{t}} ; p(0)=100$$
