Differential (change), abbreviated as \(\Delta\) (Greek symbol Delta) or DIFF, is the quantitative difference between two or more forces, pressure, time, etc. 

Differential equation is an equation which contains one or more terms and the derivatives of one variable with respect to the other variable.

  • \(\large{ \Delta }\) (Greek) = Meaning: finite, perceptible change - Usage: to find the difference.    
    • means a change in some variable.  Operation:  \( \Delta = initial - final \)  or  \({\large \frac{ \Delta y }{ \Delta x } = \frac{ y_i \;-\; y_f }{ x_i \;-\; x_f}   }\)
