Hi I'm trying to integrate a function that is the derivative of
another function, but I get a long train of errors. The error is
really long but ends up with "raise CoercionFailed("expected Number
object, got %s" % a)
CoercionFailed: expected Number object, got +inf"
My code:
from sympy import symbols, Symbol, ln, diff, exp, integrate
y = Symbol('y')
def prob(b_y,y1,y2,p1,p2):
v1=b_y*(y1-p1)
v2=b_y*(y2-p2)
return exp(v1)/((exp(v1)+exp(v2)))
print integrate(-y*diff(prob(.05,80.,y,5,2),y),(y,80.,85))
