The integral of sin2x cos2x without using the (U) way

@aurithrabarua4698

@@Osama12231 Easy man, bring on a 2, but in the same way we have to divide by two or multiply by 1/2, then it will represent a formula of sin2x=2 sinx cosx, so the expression will be sin4x and a half as a mutiple. Just because 1/2 is a constant term, bringing forth of the integral sign, we will integrate. the answer will be -1/8 cos4x

Steve and Dr. Payam, I LOVE your enthusiasm--I found myself nodding when I learned something new and smiling at how many areas of math the solution touched on :-) Thanks so much!!

I love your videos so much. Thank you a billion times. You are saving my semester!!!

Thanks a lot for deriving the general solution for complex roots. Fantastic!!!

I am so grateful for the efforts you put in your explanations, i aspire to become such a great teacher as you clearly are, keep up the great videos you're making and Thanks a million!

Have you become the teacher you always wanted to be?

I like this fast presentation method for video learning. The pause and replay buttons get used a lot, but there's nothing wrong with that!

Thanks so much for the explanation and examples! The Euler differential equation was something I was really trying to come to terms with.

Never speedrun such differential eqns ever again. Everything went over my head...but that complex part was 🔥🔥

I really like your enthusiasm and love for mathematics!! good video

You are not aware of how much has this video helped me

Thank you at thousand times from my soul(от души)☺☺☺

gute Besserung, und ich weiß, dass du bald sehr glücklich sein wirst!

Great explanation! Fast and Easy to understand

This dude is a beast. Thanks for the explanation!!!

Bprp I always love your videos! They're through and well explained! I wish you were my teacher! Your students are lucky!

You used different variables than my professor. But explained it 10x better. Thank you!

Love both channels!

As you have Euler, you have also Bernoulli, than Rickety, than etc...It’s nice to remember those college days...Thank you!

This is so cool my man I miss class but yeah you got me! thanks so much

Cool! I absolutely love your videos man! Thanks for making a 14 (almost) year old like me discover his passion for calculus and learning about integrals and derivatives! Thanks a lot man, I really mean it. Keep it up. Edit: Also I forgot to say: Good luck in your recovery Lars!

I want to give you a thousand likes

Im happy

I got everything but you didn't convince me that there aren't any different solutions. You just assumed in the begining that y=x^r but what if it's not the case.

@tagekumarpaul7474

in the observations he said that the solution needs to be focused around powers. Simply put, the solution for these types of equations have to be something that differentiates into a similar value (not too different). Thus when you plug it back in, it will give you the original equation. Also he proved that after.

.. and because of case 2 I prefer to change independent variable x=e^{t}

Since, i, is a constant it is encompassed within, "c2"....

to solve the ODE you need to change the variable by putting Z(t)=Y(exp(t))

Hello @blackpenredpen, you say at 7:10 to use x^r1*ln(x) as the other independent solution if r1=r2. However, when I tried with the diff. eqn. you formed with y=x^4 as the solution in the beginning, i.e., x^2y'' + xy' - 16y = 0, x^4*ln(x) does not satisfy this differential equation... did I misunderstand you ? Could you please explain ?

We can.

Why exactly do you in the third case take the sin and cosive as the solution? It seems to me that it should only be two cosine functions, after you plug in the +- beta part.

Is there a video that shows this when the differential equation is not equal to 0
