I seem to be a bit stuck on a problem. Consider a block sitting on a ramp, both of which are on a table. Assume that the friction between the ramp and the table is 0. Then, the forces acting on the ramp are gravity, a vertical normal force from the table, and an angled normal force from the...
Recently, I've been working on a program to simulate diffuse light, and I've hit a snag. I need to solve (at least so that a computer can compute L(x) quickly) something of the form:
L(x)=T(x)+c\int_0^{l_2}\int_0^{l_1} W(x,u_1,u_2) L(u_1) du_1 du_2
W and T are pretty well behaved, and...
