    Simple Constraint Equation Question

    Homework Statement Could you write the constraint equation for this system by using the only coordinates given in the question. (x1 and y1 for the center of mass m and X is the x coordinate of wedge) http://img602.imageshack.us/img602/34/imagea.jpg...

    What Is the Value of n in the Given Reflectivity Equation?

    but the imaginary part has n and also k, but i need to find k as an equation that i have read above. but i could't. if one of member can solve , i would be appreciate. i am very sorry for spending ur time.

    What Is the Value of n in the Given Reflectivity Equation?

    Homework Statement sqrt(R)*(cos a + i sin a) = (n - ik - 1) / (n - ik + 1) what is n in terms of others. "i" is imaginary part. By using this equation, can you separate imaginary and real part for finding R= (1-R) / [1+R-2*sqrt(R) * cos a] and K = 2 * sqrt(R) * sin a / [1 + R - 2...

    What Are the Singularities and Residues of the Function z^-n(e^z-1)^-1?

    In complex analysis, there are four kinds of singularity, to be described below. Suppose U is an open subset of the complex numbers C, and the point a is an element of U, and f is a complex differentiable function defined on some neighborhood around a, excluding a: U \ {a}. * Isolated...

    What Are the Singularities and Residues of the Function z^-n(e^z-1)^-1?

    Homework Statement z^-n(e^z-1)^-1 , z not equal to zero locate the singularities and evaluate the residue. Homework Equations The Attempt at a Solution i don't have an idea about when z is not equal to zero because i think that only singularity point is z=0 hence if there...
