hi
i was trying to plot the equation
u(x,t) = x- (2/pi) exp(-pi^2 t) sin(pi x) for x= 0 to 1 and t =( 0, inf)
onto maple and this was what i typed
plot3d(x-2*(-exp*pi^2*y)(sin(pi*x))/pi, x = 0 .. 1, y = 1 .. 100)
but maple kept saying that it was incorrect..
may i know what is wrong with my maple input?
thanks!
