I have 2 brothers and 2 sisters. My mother said if we were good, we would get our allowance. The 5 of us were playing catch in the house. When I tried to catch the ball, I accidentally knocked over my mom's decorative vase and it broke. Needless to say that we did not get our allowance. It cost $50 to replace the vase. My brothers and sisters agreed to share the cost. How much did each person earn?
It's kind of silly, but that's all I can think of.
The general solution of a differential equation of the form ay'' + by' + cy is given by Ae^mx + Be^nx; where m and n are the root of the quadratic equation ax^2 + bx + c
The general solution of <span>y'' + 4y' is given by </span><span>Ae^mx + Be^nx; where m and n are the root of the quadratic equation x^2 + 4x = 0
x(x + 4) = 0
x = 0 or x = -4
Therefore, the general solution is Ae^(-4x) + Be^0x = Ae^(</span>-4x) + B
