Hello, I am having trouble plotting this function:
sage: plot3d((math.sqrt(2**3))*math.exp(-(x**2 + y**2)), (x, 0, 5 ), (y, 0,
5))
plot3d((math.sqrt(Integer(2)**Integer(3)))*math.exp(-(x**Integer(2) +
y**Integer(2))), (x, Integer(0), Integer(5) ), (y, Integer(0), Integer(5)))
/home/sem/SageMath/src/sage/symbolic/expression.pyx in
sage.symbolic.expression.Expression.__float__
(/home/sem/SageMath/src/build/cythonized/sage/symbolic/expression.cpp:11265)()
1411 raise
1412 except TypeError:
-> 1413 raise TypeError("unable to simplify to float
approximation")
1414 return ret
1415
TypeError: unable to simplify to float approximation
I can't find the error here. Can anyone help?
Many Thanks!
