great explanation, I had not thought of this idea. greetings from Colombia ¡¡Grande Mister!!

[Sumayra]

I have a final tomorrow regarding these chapters, I cannot tell you how grateful Iam! Thank you so much!

[DanteRamirez]

Gracias!!! Excelente video, saudos desde Perú.

I think.. If we integrate a function of type f'(x)/f(x) we will always get ln|x|+C. 😀

[stewarthills]

Well spotted it would have taken me a few hours or days to have thought of doing it that way! Good job!

I literally mastered integration to a degree that I'm confident I'll do well in any exam with decent difficulty then the pandemic hit and I forgot everything 😭

[utubefreak]

I am so impressed, thank you for this

[nirupamamondal]

Thanks for the great explanation.
I like it. Thank you.

[trinhduong]

Could you explain me why dx=du/(sinx+cosx). I don't understand :(

[shyamprakash]

u r awesome man thats an easy trick✌😎😘

[samuraix]

Wow, you are an excellent teacher!!! 💘💘💘💘💘💘💘💘👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻

[samyaksaranprasad]

thanks.any direct methods for this????

[tanishka_bhu]

Wow wonderful explained it seems to easy now . 👏👏👏👏

He is the real mathematician because he does all tuff problems

[Starlordsstudio]

= (1/2) [ x + ln | sin x + cos x | ] + C ... This is the
Ans.

[holyshit]

Substitute u=tan(x)
Int(1/((u+1)(u^2+1))du)
