Homework Statement
Derivative of an integral function. [tex]\theta[/tex] is a function [tex]\xi[/tex] and [tex]\tau[/tex](space and time variable)
Homework Equations
cos[tex]\theta[/tex][tex]\frac{\partial}{\partial[tex]\tau[/tex]}[/tex]([tex]\int[/tex]
sin[tex]\theta[/tex]d[tex]\xi[/tex]).
The limit running from -[tex]\infty[/tex] to [tex]\xi[/tex]
[tex]\theta[/tex][tex]\rightarrow[/tex] zero as [tex]\xi[/tex][tex]\rightarrow[/tex] to -[tex]\infty[/tex]
I want to eliminate the integral by differentiating the above equation with respect to [tex]\xi[/tex] once.
The Attempt at a Solution
I simply differentiated with respect to [tex]\xi[/tex] by product method of differentiation.
but still integral retained in the final equation
This problem i encountered in journals.
