This is because when you type "from scipy import integrate" you are
overwriting the integrate function. (There can only be one thing named
integrate at a time in a given scope.)
sage: type(integrate)
<type 'function'>
sage: from scipy import integrate
sage: type(integrate)
<type 'module'>
You can get it back with reset.
sage: reset('integrate')
sage: type(integrate)
<type 'function'>
sage: maxima(integrate(cos(3*x)^4))
sin(12*x)/96+sin(6*x)/12+3*x/8
