Dear excel, first of all, thanks for teaching from you, how fix the value error for QUADF Function in excel, I have more complexity function and then can't detect error exactly is, while checked entire calculations from inputs to this error, please help me and of course I installed related add-in

When we type X1 or Y1 as variables, doesn't Excel consider the CELL X1 and not the variable x?

sir how can i implement this function "INTEGRAL(SIN(50*COS(x)))dx" with limits 0 to pi

[@excelworksllc1994]

This is a trivial 1D integral
1) install calculus add-in from excel-works.com to enable QUADF() function
2) define your integrand formula in some cell A1 '=SIN(50*COS(x1))'.
3) in a second cell A2, use QUADF to integrate. '=QUADF(A1,x1,0, PI())'
see examples at excel-works.com.
