Starting at t 0, a concentrated load of magnitude F0 moves with a constant velocity v0 along a semi-infinite string. In this case the wave equation becomes a2 02 u 0x 2 02 u 0t 2 F0d at 2 x v0 b , where d(t x/v0) is the Dirac delta function. Solve this PDE subject to u(0, t) 0, lim xSq u(x, t) 0, t . 0 u(x, 0) 0, 0u 0t 2 t0 0, x . 0 (a) when v0 a, and (b) when v0 a.

MATH121 Chapter 2 Notes LESSON 2.1 – Linear Equations in One Variable Example 1. 6(5x - 5) = -31(3 - x) (Multiply 6 and 5x, and 6 and -5) (Multiply -31 and 3, and -31 and –x) 30x - 30 = -93 + 31x (Get similar values on same sides) -x = -63 (Divide by -1 to get x by...
