Convert this relation to a function

SUMMARY

The discussion centers on converting the relation tan y = (Vsin(y) - gx) / Vcos(y) into an explicit function y = f(x) with respect to the variables V, x, and g. The variable g is defined as a constant, while V is expressed as the function V(x) = -aln(b/(b - cx)) - dx, where a, b, c, and d are also constants. The conclusion drawn is that an explicit function cannot be derived from this relation, indicating a need for alternative modeling approaches for the angle of attack of a rocket projectile.

PREREQUISITES

can anyone convert the relation tan y=(Vsin(y)-gx)/Vcos(y) to an explicit function y=f(x) in terms of V, x and g?

g is a constant
V is the function V(x)= -aln(b/b-cx)-dx

a,b,c,and d are also constants.

Thanks!

tany = siny/cosy, so unless cosy = 0, you have:
Vsiny=Vsiny-gx
or go back one step and you have tany = tany - gx/Vcosy.

In any case, there is no function.
 
I was afraid of that. This relation was supposed to model the angle of attack of a rocket projectile. I guess I'll have to derive a different way of modeling it. Thanks!
