All drag is equal to this equation:
D = Cd1/2pV^2S Where:
Cd is the drag coefficient.
p is air density
V^2 is velocity squared.
S is frontal surface area.
This incorporates both induced and parasite drag. The reason induced drag increases with a lower velocity is both the surface area and drag coefficient increase greatly as you fly slower, but physically it is no different than parasite drag. If you put an aircraft model in a wind tunnel at a fixed high angle of attack (like for slow flight) and increased the airspeed, the drag would increase like parasite drag. It would be incorrect to split the two types of drag up based on drag coefficient alone (Cdi and Cdp).

Mathematically, I don't know the formulas...but socially, these would b the formulas:
Induced Drag= Man Forced to Wear Women's Clothing
Parasite Drag = Insect wearing lady's clothing

Induced Drag Equation
Di = Cdi x S x ½ rV2 ... where
Di = Induced Drag
Cdi= Coefficient of Induced Drag
r = Air density
V = Velocity

The equation for the lift induced drag coefficient of a fixed wing is:
CDi = CL^2 /(pi*A*e)
CDi = induced drag coefficient
CL = lift coefficient
A = aspect ratio
e = Oswald span efficiency factor
