Hello, I am having trouble plotting this function:
sage: *plot3d([(-t+x)^(0.5)*(sech[(t-x)^2]^2)] (x,-5,5), (t, -5, 5))*
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-10-44b4efea1b7c> in <module>()
----> 1
plot3d([(-t+x)**(RealNumber('0.5'))*(sech[(t-x)**Integer(2)]**Integer(2))]
(x,-Integer(5),Integer(5)), (t, -Integer(5), Integer(5)))

self)
1078 if isinstance(n, sage.rings.integer.Integer):
1079 return n
TypeError: unable to convert (t - x)^2 to an integer
I am not sure what this is caused by, Both x and t are defined as
variables, but it asks for an integer .
Thanks
