How to find partial derivative of dependent variable at one point

My equation of cb requires me to input "partial derivative of cp at x=0"
i,e cb=k*pd(cp,x)|(at x=0)
k is constant.
And in calculation of cp my boundary conditions for it are at x=0 and L cp=cb. There is no cb in the differential equation of cp except for boundary conditions.
How am I supposed to calculate partial derivative of cp at x=0?
Please Help
Thank You
