微积分问题,主要是看不懂题干,真不知道是应该说是英语问题,还是数学问题……
When a mass m on the end of a spring is pulled down and then released and the resulting motion is subjected to a damping force proportional to the belocity then the motion is described by the D.E.
d^2y/dt^2+cdy/dt+ky=0
Where y is the displacement from the equilibrium position at time t.
a. Suppose the D.E. is d^2y/dt^2+4dy/dt+3y=0
Show that y=e^-3t is a solution to this equation.

证明 y=e^(-3t)是微分方程d^2y/dt^2+4dy/dt+3y=0 的一个解
其中y是在时间t时离开平衡位置的位移
你直接将y=e^(-3t)带入d^2y/dt^2+4dy/dt+3y=0验证即可
D.E.是微分方程的意思
