Why the following code does not work with SageMath version9, though it works with SageMath version8?
f(x,y)=sin(x+2*y) numerical_integral(f,0,pi,params=[5])
SageMath version8.6 gives (-1.6781430581529053, 2.2206773047754592e-14). SageMath version9.7 gives (0.0, 0.0).
Execution of numerical_integral(f(x,5), 0, pi) in SageMath version9.7 also gives (-1.6781430581529053, 2.2206773047754592e-14).
