[itex]tan[/itex][itex]([/itex][itex]x[/itex][itex])[/itex][itex]=[/itex][itex]k[/itex][itex]\frac{x}{z^{2}}[/itex](adsbygoogle = window.adsbygoogle || []).push({});

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.
