I'm trying to implement the equations for a parabolic show with small damping forces (the ones that exists when the projectile is shot in the air)

The equations are those:

$\displaystyle X(t) = X_0 + \frac {V_{0x}} {b} \left(1- e^{-bt} \right)$

$\displaystyle Y(t) = Y_0 + \frac {1} {b} \left( \frac {G} {b} + V_{0y} \right) \left( 1-e^{-bt}\right) - \frac {G} {b} t$

Where:

t = the current equation time

b = c/m

c = the damping coefficient

m = the projectile mass

G = the gravity acceleration

and $\displaystyle V_{0x}$ , $\displaystyle V_{0y}$ , $\displaystyle X_0$ and $\displaystyle Y_0$ are the initial conditions for velocity and position.
