I try to use walfram mathematica to compute a double integral, my code is
Integrate[0.5*exp[-90*(x - 0.5)^2 - 45*(y + 0.1)^4] + exp[-45*(x + 0.4)^2 - 60*(y - 0.5)^2], {x, -1, 1}, {y, -1, 1}]
while the output is just a simplify, not a result. Then I try to use walfram alpha online with the same code, andbut it gives the anwser. I'm really confused!
