## Geometrical and Physical interpretation of Derivative

Geometrical Meaning of Derivative:
The interpretation of derivatives as a geometric meanings has important applications and will therefore be discussed now.
Let y=f(x) be the equation of line represented by the curve po p shown in the following figure.
The difference quotient
is the slope of the secant line joining P0P of the curve. When , the secant line approaches to the tangent line at P0
Thus,
is the slope of the tangent to the curve at point P0.
Thus, geometrically derivative Read more [...]
