Equation of parabolic curve y=(NX2)/(2L).
Where N is gradient N=n1-n2.
n1 is positive for downward gradient.
n2 is negative for upward gradient.
So N=g1-(-g2).
N=g1+g2.
Finally y=(g1+g2)X2/(2L).
Where N is gradient N=n1-n2.
n1 is positive for downward gradient.
n2 is negative for upward gradient.
So N=g1-(-g2).
N=g1+g2.
Finally y=(g1+g2)X2/(2L).
