After watching this video you will understand that ... A line integral is the generalization of simple integral. A surface integral is generalization of double integral. A volume integral is generalization of triple integral.

I have done all my maths without understanding & now I have got the gist of those maths by this, thanks to it's creator. May AllaH bless him or her.
Great work! If only they taught like this in school
Please continue your work .....don't stop...👍
The best explanation
I have no idea how do you guys understand this so easily but even after watching the video I was no able to grasp properly.
You've helped me to understand it very accurately than mugging it up.
really helpful to understand the concepts. Vivid demonstration. Thanks a lot you made my day😍
Excellent👍
Keep doing such videos
Keep up the good work💕. We want these type of videos many more.
Amazing the way of teaching is jss...outstanding....I am worried why this channel is not growing as per its potential.....
I still not understand...cal3 is toooooo hard!!!! but this video is beautiful
I wish these videos were available when I studied engineering

Simple integral: ∫dx
Double integral: ∬dA = ∬dydx ∬ rdrdθ
Triple integral: ∭dV = ∭dzdydx = ∭rdzdrdθ = ∭ρ^2*sin(φ)dρdφdθ
Line integral: ∮ F ∙ dr = ∮ (F ∙ n)ds = ∬(Ny-Mx)dA = ∯ curl F ∙ dS = ∫y(x)√(1+(y')^2)dx = ∫r(t)√((x')^2+(y')^2)dt = ∫r(θ)√(r^2+(r')^2)dθ
Surface integral: ∯ F ∙ dS = ∯(F ∙ N)dS = ∬z(x, y)√(1+zx^2+zy^2)dydx = ∬r(s, t)√(rs ⨉ rt)dsdt = ∬g(x, y, z) * ∇g/(∇g ∙ n)dA = ∬r(θ, z)√(r^2+rθ^2+(r*rz)^2)dθdz = ∬ρ(φ, θ)√((ρ^2*sin(φ))^2+(ρ*sin(φ)*ρφ)^2+(ρ*ρθ)^2)dφdθ
Volume integral: ∰ F ∙ dS = ∰(F ∙ N)dS = ⨌dV = ⨌dwdzdydx = ⨌rdwdzdrdθ = ⨌r1r2dr2dθ2dr1dθ1 = ⨌ρ^2*sin(φ)dwdρdφdθ = ⨌р^3*sin^2(φ)*sin(ψ)dрdφdψdθ
Using Green's Theorem, you can convert a line to a surface integral.
Using the Divergence Theorem, you can convert from a surface integral into an interior integral.
Amazing video
Thanks ^^
This is great. Too bad we don't have holograms in schools.
Yes

You never be a good teacher. What is in your mind is different to the others. If some people knew these kind of integral no need to listen to you. You just lecturette for the people that they knew these subject.
