# Need help in solving this eqn

$tan$$($$x$$)$$=$$k$$\frac{x}{z^{2}}$

where k is the constant of proportionality, y varies according to x and z. x and z are independent constant values. I need to first find the value of the constant "k" and then find y for corresponding "x" and "z" values.

I think there might be a few typos in there. There is no "y" in your equation, and if "x" and "z" are "constant values", with "k" a "constant of proportionality", then the left side is a number (since the tangent of a constant number is constant), and the right side are all constant.

Oops. First time with latex. My apologies. Here's the intended eqn.

$tan$$($$y$$)$$=$$k$$\frac{x}{z^{2}}$

In order to find k, you must be given a single (x, y, z) point.
