Calculation of area of a triangle using integration

[mrgenius4]

Thank you !!

[joeymorrow3]

Where do you get the "2" from at 2:44?

[ghostly65]

@joeymorrow3 the integral of x is x^2/2

[12arachne]

omg thank you.

[XANDERXXZ]

Why do you do your multiplication signs as dots? its realy confusing.

[illustriouschin]

@XANDERXXZ Dots are how grownups multiplicate.

[XANDERXXZ]

@illustriouschin Ohh HA HA HA

[XANDERXXZ]

@XANDERXXZ That was sarcastic by the way

HELPED ME SO MUCH you have no idea, this was bugging me all day - 1st year engineering student :)

[TheRealDamnSyko]

Can I have you as my lectruer instead of who I have now? :D

[warpedset]

you should do the proof for the therom of any triangle. A= 1/2 ab Sin C

Thats the equation I though you would have produced when I clicked you're video. Nicely constructed though.

[MG0808]

thanks this really helped me!!!!

[lamchee58]

Nice work indeed.

[cactuscity]

You have proved for right-angled triangles only...

[lamchee58]

Dear cactuscity,

consider other triangles to be made of two right angle triangles.

[cactuscity]

Correct, though he didn't explain/prove that.

[Tonyjava]

Watch the video twice, once for each RA triangle then.

[ccchappa]

Nice presentation. Two comments.

1) You really just proved your formula for a right triangle whose base and height are the legs, and not a triangle in general. Yeah, I know, the formula in general follows from this specific case. Just being picky.

2) I think your videos are very well suited for students who have a good grasp on math to begin with, but can easily lose someone who kinda knows, but feels unsure about certain moves.

Hmmm, maybe I should try this teach via YouTube schtick

"2) I think your videos are very well suited for students who have a good grasp on math to begin with, but can easily lose someone who kinda knows, but feels unsure about certain moves."

- I Agree with you dude. I'm kinda lost. I know the concept of integrals a bit but this is kinda next level teaching.

[kalaila9]

Can you do this in english? Wait neve mind I got a C in that class too.

Damnit I am screwed.

[bkjoelover]

am i the only one that thinks your video audio output is dead on the right side?

[midnighttutor]

ooops you want stereo????  well of course that costs extra.....

[bkjoelover]

no... surround sound, jp.

[sprocketman14]

Man do I feel stupid.

[Theauthenticmindset]

i miss calculus class

[MisterSym]

Great use of calculus to relate to earlier math.

[krille1977]

This is great. useful. It is a very good way to learn mathematics.

[48phantom]

I am positive that you have the ability to teach more advanced calculus topics. But this demonstration is excellent! I look forward to watching more. Thank you. :)

Thanks for taking the time to post this.
