Gradient of a Scalar Field Explained | Vector Calculus for CSS & Engineering Students

Описание: Master the concept of Gradient of a Scalar Field (∇φ) — one of the most important foundations of Vector Calculus, Physics, and Engineering Mathematics.

In this lecture, we break down:
✅ What is a scalar field?
✅ What does gradient actually mean?
✅ Direction of maximum rate of change
✅ Why gradient is perpendicular to level surfaces
✅ Mathematical derivation using partial derivatives
✅ Real-life applications in Pakistan & worldwide
✅ Solved examples for CSS, Engineering & University exams
✅ Visual demonstration with contour maps and gradient arrows

Whether you're preparing for CSS Applied Mathematics, Engineering exams, or simply want to strengthen your calculus fundamentals — this video is your complete guide!
