Defining a function as definite integral

Abhijit Bhattacharyya

Please login with a confirmed email address before reporting spam

Hello! I have some parameters which need to be defined as Par1 = const1 + Func1(x) with some given x as real number. The function Func1(x) needs to be defined as Func1(x) = integrate(1.0/(1- x * x * sin(y) * sin(y)), y, 0, pi/2).

If I try to define using Analytic in Global definition, I need to define function with two arguments x, y while y should not be supported as it is defined in the definite integral limits.

If I try to define as parameter then I cannot define it as Func1(x) but as just Func1 means I am unable to supply argument values.

Since Func1(x) is basically complete Elliptic Integral, I tried to search pre-defined integral function in COMSOL which I did not get. Please give me handle how may I resolve this issue. Thanks and Regards Abhijit
