Dairy  = 6 * 12   = 72  in all

Beef = 4 * 16  = 64 in all

8 more dairy

Guess it depended on the gas station, EP.......LOL!!!!!

Also.....some polar plots can produce some pretty neat looking graphs :

According to this :  http://www.usinflationcalculator.com/......it would cost you $26.63 to fill your tank in 2000......

Max....maybe you're after somehing like this ???

 x / t  = cos (t)

[x / t] ^2  = cos^2(t)

[x / t] ^2 = 1 - sin^2(t)

[x / t] ^2  = 1 - [ y/t] ^2

[x / t] ^2 =  [t^2 - y^2] / t^2

x^2  = [t^2 - y^2]

y^2  = t^2 - x^2    take the + root

y  =  √ [ t^2 – x^2]

y  = √ [ t^2 – t^2*cos^2(t) ]

Compare the graphs

1 / [3^(1/3) + 2^(1/3) ] 

We realize that the denominator can be made to be a sum of cubes if we multiply  numerator and denominator by  [3^(2/3) - 3^(1/3)*2^(1/3) + 2^(2/3) ]

[3^(2/3) - 3^(1/3)*2^(1/3) + 2^(2/3) ] / ( [3^(1/3) + 2^(1/3) ]  [3^(2/3) - 3^(1/3)*2^(1/3) + 2^(2/3) ] )

[3^(2/3) - 3^(1/3)*2^(1/3) + 2^(2/3) ] /  [ (3^(1/3))^3  + (2^(1/3))^3 ]  =

[ 3^(2/3) - 3^(1/3)*2^(1/3) + 2^(2/3) ] / 5  =

[3^(2/3) - 6^(1/3) + 2^(2/3) ] / 5  =

[ ∛9 - ∛6  +  ∛4 ]  / 5
