From basic formulas to implicit and logarithmic functions.

Often a difficult topic for students, handled here with step-by-step derivations.

. This ensures that students understand the "smoothness" required for a function to be differentiable before they ever apply a power rule.

Differential calculus is a fundamental branch of mathematics that deals with the study of rates of change and slopes of curves. One of the most popular textbooks on differential calculus is "Differential Calculus" by Das Gupta. In this article, we will review the book and provide an overview of its contents, highlighting its strengths and weaknesses.

The book is structured to guide students from foundational limits to advanced multidimensional calculus. Key topics typically include: Foundations
