    lol my head is about to explode! :P

    i think this is similar to a previous question i asked but i can't quite get it none the less...

    now what i did was to following this :

    then using equations (31) & (32) from that i just plugged in the values and got:

    u(x,t) = 1 for x > ct and u(x,t) = 0 for 0 < x < ct

    how does this look to you intelligent mathematically inclined people? :S

    Sarah :)

    but then how do you find a singularity when you have an answer of 1 and 0? :S
