Explanation Formula used: Δ φ = ∂ 2 φ ∂ x 2 + ∂ 2 φ ∂ y 2 + ∂ 2 φ ∂ z 2 Proof: Let us consider F = F 1 i + F 2 j + F 3 k . Let us first find an expression for the left-hand sine: C u r l ( F ) = ( ∂ ∂ x i + ∂ ∂ y j + ∂ ∂ z k ) ( F 1 i + F 2 j + F 3 k ) C u r l ( F ) = | i j k ∂ ∂ x ∂ ∂ y ∂ ∂ z F 1 F 2 F 3 | = i ( ∂ F 3 ∂ y − ∂ F 2 ∂ z ) − j ( ∂ F 3 ∂ x − ∂ F 1 ∂ z ) + k ( ∂ F 2 ∂ x − ∂ F 1 ∂ y ) C u r l ( C u r l ( F ) ) = | i j k ∂ ∂ x ∂ ∂ y ∂ ∂ z ∂ F 3 ∂ y − ∂ F 2 ∂ z ∂ F 3 ∂ x − ∂ F 1 ∂ z ∂ F 2 ∂ x − ∂ F 1 ∂ y | C u r l ( C u r l ( F ) ) = i ( ∂ 2 F 2 ∂ x ∂ y − ∂ 2 F 1 ∂ y 2 − ∂ 2 F 3 ∂ x ∂ z + ∂ F 1 ∂ z 2 ) − j ( ∂ 2 F 2 ∂ x 2 − ∂ 2 F 1 ∂ x ∂ y − ∂ 2 F 3 ∂ y ∂ z + ∂ 2 F 2 ∂ z 2 ) + k ( ∂ 2 F 3 ∂ x 2 − ∂ 2 F 1 ∂ x ∂ z − ∂ 2 F 3 ∂ y 2 + ∂ 2 F 2 ∂ y ∂ z ) Let us now find an expression for right-hand side: ⇒ d i v ( F ) = ∂ F 1 ∂ x + ∂ F 1 ∂ y + ∂ F 1 ∂ z ⇒ ∇ ( d i v ( F ) ) = ( ∂ ∂ x i + ∂ ∂ y j + ∂ ∂ z k ) ( ∂ F 1 ∂ x + ∂ F 1 ∂ y + ∂ F 1 ∂ z ) ⇒ ∇ ( d i v ( F

Arc Length

Arc length can be thought of as the distance you would travel if you walked along the path of a curve. Arc length is used in a wide range of real applications. We might be interested in knowing how far a rocket travels if it is launched along a parabolic…

Line Integral

A line integral is one of the important topics that are discussed in the calculus syllabus. When we have a function that we want to integrate, and we evaluate the function alongside a curve, we define it as a line integral. Evaluation of a function along…
