Hi, how does one write 10^(-8) ?
Is it as the conventional way 10**(-8) or is it 10exp(-8) ?

Hi, I tried many re-edits, and found a few errors along the way, however,
there seems not to be any errors left, still nothing happens when issuing
the plot3d command:
plot3d(lambda x,y:(exp(I*2000*(1.60217662*10**(-19))/(299792458*6.6260700*
:
10**(-34)))-(sqrt(I*(1.60217662*10**(-19))/(4*
Changed to:
sage: plot3d(lambda
x,y:(exp(I*2000*(1.60217662*10**(-19))/((299792458*6.6260700

Hi, I was wondering if SAGE can be used to solve a PDE in the form:
u(x,y)''+u(x,y)' + const = 0
?
Thanks!

Note, that when brackets are corrected it gives the following result:

Hi, I tried to use a command found online for plotting complex and real
components of a function:
var('x y');
cmsel = [colormaps['gnuplot2'](i) for i in sxrange(0,1,0.02)]
plot3d(lambda
x,y:(1/(math.sqrt((2**2)*pi)))*(x+I*y)*exp(-((0.25)*((x+I*y)**2.imag_part(),(x,-3*pi,3*pi),(y,0,2),adaptiv
something stops here.
Is this a wrong type of way of plotting that function?

Hello, I tried a different variant of the previous plot:
def f(x,y):
return math.sqrt(2**3))*exp(-(x**2 + y**2)
P = plot3d(f,(-3,3),(-3,3), adaptive=True, color=rainbow(60, 'rgbtuple'),
max_bend=.1, max_depth=15)
P.show()
however, this also does not show.

Hello, I tried to plot plot f(x,y,z)=x+y+z but couldn't get a plot. I
thought this was because of the 4D nature of the plot, however, when trying
on Wolfram alpha, it gave quite a strange plot.
How can this type of functions be plotted, and were is in so case f(x,y,z)
(on which axis) ?
Thanks
