Good bro..
Greetings. I got two answers, 43, 3. However, 43 yields a negative 2 whwn it is plugged into the original expression. Three is the only value that satisfies the expression.
Yeah that's why one has to always check for extraneous solutions...
Too slow n too long
Will work it boss...
You are good snr..!
I hope you are enjoying it...
The other one gave me the same answer...
Then keep watching bro...
J= ln(3/(e+1))
Was it difficult after the substitution
Thanks for making my understanding clear on completing square method . I used to struggle with it
You are most welcome
For both sides, multiply by 3 --> square --> subtract 2.
Sure in one minute
What other approach can be use
Lambert W function or absolute value approach
@@MathInTwi. Use the lambert w function to solve it ...
I used to have problem when computing the values after integration. But now I how, thanks..
Keep watching
What all do you use?
Please I don't get you
@@MathInTwi. i meant what writing app do you use
will be waiting..
Promise honored
Impressive ❤
Thanks..
u need to be making this video 5 minutes long, not 50. People who want to go slower can slow the playback speed on RUclips. If u just did u = sqrt(x^2+9), then u^2 - 9 = x^2 and 2u du = 2x dx ==> u(u^2 - 9) du = x^3 dx, So your integral becomes over u^2 - 9 du which is really obvious. Could’ve saved yourself 50 minutes too
Sure thanks
@@MathInTwi. keep doing what u are doing, just constructive criticism to present solutions faster. Didn’t mean anything in a rude way
Are you fucking crazy to solve this at that rate.
If you take such a long time to solve this simple problem, you are bound to fail in all the exams....a tortoise will do this faster than you !
Will try and go fast next time ...
It is easier to substitute u² = x² + 9 which at once removes the square root and leads to a simple integration of (u² - 9)du
Sure thanks...
i can confirm, i did the subsititution and got the same answer in 5 minutes, very easy method, thanks!!
Good
Thanks
What a stupid and long video.
Good.
Thanks
Just by looking at it I can say x = 16
Good
I like the approach used
Thanks
Wow , u make the solving of indices so simple , keep up the good work
Thanks
At first I used wonder why integral of sinx gives -cosx. But thanks to MIT maths I now know why. Waiting for more
Keep watching
Keep broadening our mind on calculus
Thanks keep watching. More to come
cool we will be waiting
Thanks keep watching
Thank God I now know how to use the indices method to solve questions of this nature. Waiting for more...
Keep watching
