Essay: Differential Calculus — Abdul Matin (PDF, New)

The derivative is the central object of study in differential calculus. Geometrically, it represents the slope of the tangent line to the curve ( y = f(x) ) at a point. Physically, it represents the instantaneous rate of change. The definition arises from the difference quotient: [ f'(x) = \lim_h \to 0 \fracf(x+h) - f(x)h ] provided the limit exists. A function is differentiable at ( x ) if this limit exists, and differentiability implies continuity (though the converse is false).

Digital copies are primarily available through community-uploaded repositories.

• Read a solved example from the book.
• Close the book.
• Try to write the solution yourself. If you get stuck, open the book only for that specific step.
