Calculus: Integrals 6

[shirleybreeze]

this is awesome

[vhdesouza]

i dont get the trick in the last integral too

[MrSuperdrama]

THANKS OLD MAN..THANKS MATH TV

[mikkrobio]

This person reminds me of Dexter! Look at the similaritys in facial expression :D

[blackdefender]

Can someone help me. I got this question which I can't solve (I'm not really good at this). Anyway, I have here: {(X+6) / (X+2)^2} dx and I have to find the integral of it...well our teacher said it's quite challenging and it really is...can someone care to help?

[maj2much]

thanks for this video..its a big help for my exam today

[MrRkesh]

i dont understand the last integral, what's long division ?

[Balkance]

we learned that long time ago.. i forgot it kinda.. it's a type of division that will actually show you a visual remainder.. ughh.. i don't understand it either..

[Never1st]

@MrRkesh google 'polynomial long division wiki'

[xReirax]

Thanks so much for this. Looks like I'll be passing my calc test!!!

[shankylalia01]

hi i had a problem in one question in integration by substituition the question is

x / under root x+3 dx, if u can help me

[Brain704]

omg like these problems are easy compared to the 20 parts ones my teacher gives us. i dont know about you but i like easy :)

Part of the fun in calculus is figuring out what trick will be used, and some teachers may give one or two "interesting" problems on a test. I saw one problem on a test that called for multiplying by a conjugate and then remembering a trigonometric idenity, which was sine squared plus cosine squared = 1.

[jackysspauli]

You're right, figuring out what trick must be used is part of the fun but it's also what makes calculus quite difficult from a certain point. Some people find the trick rapidly and some don't. I love calculus but i'm not good at figuring out what trick or what identity must be used...irony :)

[MICHAELMEMISBACL]

It is indeed helpful to remember that the radical in the denominator (which is 1/2 power) may simply call for the power rule in reverse (for integration), but other times the radical in the denominator calls for trigonometric substitution in some cases, or certain formulas that involve inverse functions.

[gcash2009]

hey uncle, another great video of yours :)

[Ritzoid]

Integral calculus is so much fun.

[D1zast3r]

this guy is better than my calculus professor

[anthonychemistry]

yes.. agree..it is obscene..

[didsomebodysayme]

that last solution was a little out there, no normal student is gonna think to use variable division

[djambe]

Actually, in my university, we need to use it at times...

[jindassasin]

Your exactly right, in some cases knowing variable division will separate the A students from the normal students.

[b0rd2dEAth]

lol i use it in ap calc at times. weve even had the same exact problem...

[wall12390]

we use it at WVU

[cocoabean]

Yea this guy rules.

[kazlon1]

what if he used the wrong marker?

[lrzn88]

Very helpful indeed. I like the idea of keeping the videos short. In that way there is no problem to keep focus on the subject. Nice complement to my calc. textbook.

[chrisortiz713]

hmm...why can't the final one be solved by substitution?

[DerbyshirePoacher]

You can get the correct result using integration by substitution.

However, in this case you will be using a hammer to crack a nut.

Mathematics for the purists is about finesse, not brute force.

[Entertainmentwf]

precisely :). Elegance is one of the most beautiful things about Mathematics :D. Besides the more elegant it gets, sometimes you learn more about the relationships in the process. Afterall, that's how some of the greatest relationships in mathematics have been found :). Nice explanation :).

[danknugzorz]

because once u differentiate for u, either the top or bottom, you are looking for an x to the 1 power to put it back in, and there is not one either way

[adityashaha]

man iam so jelous of americans

we as indians have many trouble in the class

first of all teachers are not audible to the last benchers and there writing is worst and they use pens with few drops of ink left out

and right when u understood the first half of the problem they simply rub it off the board and when u dont get nice grades they start making fun of u in the class

damn i hate indians and india on this note

[airegalado]

This is an amazingly helpful/straightforward resource..Love it. Screw my Calc. Prof., the confusing fool he is

[dekitai20]

Thank you soo much! That helps!!

[DeafGecko]

this is the best cal resource ive found outside of class, and that includes the textbook.

[xroyaldevilx]

Thanks for the video. It was very helpful.

[rodogg2092]

way better than my teacher. thanks. this really helps.

[benbear79]

I have passed tests based on what you teach me, not what my lecturer teaches, thankyou very much

[maylien]

Kudos. Very clear. My absent students will benenfit.

[airegalado]

lol, uhoh that may include me..Prof Yuzik?? haha, jkjk

[razzzzzzzz]

you are awesome. thanks

[arod889]

you should of finished how to do that problem from integrals 5 =(

[ajordanb13]

@arod889 he said it cant be done if youre talking about the last one
