Definite & Indefinite Integrals

[parasdeepsingh]

You are an absolute gun!! I feel soo bad that I didnt start looking at your videos earlier. Most teachers now days just show us HOW to do something but you also explain WHY you do and and WHY it works in detail!! Thank you soo much!

[christilane]

You’re an amazing teacher! The way you simplify these concepts is truly a gift. Thank you.

[REDandBLUEandORANGE]

Would like to let you know
I was getting 60s in calculus
Once I found your videos I am now getting 80s
My average was brought up to a 70
Thank you

I know this is an old video but it is really good! Was really struggling on this and was really worried about failing but this really helped alot, thank you

[euwenwong]

I didn’t know differentiation and integration could be related in the way you showed... THANK YOU 🙏🙏🙏🙏🙏

[blueiceani]

this is an amazing explanation. It makes me feel that math isn't too difficult to learn when it's explained well.

[louisgardiner]

Tell you what mate, these videos are top notch. Thanks for making it easier!

[HandleThis]

This is such a good video about the two THANKS SO MUCH

[joro]

So excellent. This nomenclature has confused me for years. So easy to mistake if someone does not point it out specifically

[jadebeil]

I wish you were my professor!! Thank you for all your helpful videos!

Thank you so much, this was so hard to figure out, because the big s sign is very mysterious sometimes.

The thing I’m struggling with is what does riemanns idea of making infinite rectangles actually got to do with the maths when it comes to integration?

[johanneskampfl]

Sorry, i didnt get that.
How can it be that ∫ dF is equal to F(x) + c. Because with the expression of ∫ f(x) with respect to e.g. dx you integrate a function with respect to a variable. But when you say ∫ 1 dF you integrate 1 with respect to the primitive function, so you integrate with respect to a function, which makes no sense in my opinion. I think there might be a relation and in a confused mathematical way it's surely true but I dont get it.

Damn Eddie Woo, you clearly and completely explained it within 6.5 minutes. Thank you sir. I can now go back and continue on with my actual online class.

[ahmedatifabrar]

Good. But Tom Apostol writes, primitives or antiderivatives are not exactly indefinite integrals (Calcukus, Vol I, p. 211).

[reubenkomen]

to be honest i look up to you're such a gun

Can you please help me out with this question:

Find the area bounded by the curve y=sqrt(4-x^2), the x-axis and the y-axis in the first quadrant. 

The answer is pi or 3.14units^2, but when I evaluate it, it doesn't work

Primitive Function = Antiderivative
Gradient = Slope
