Integrate x^3exp(-2x)sinx from 0 to infinity using differentiation under integral sign . I find this problem in Advance calculus explore book's gamma function chapter
I've seen the beginning before on blackpenredpen. but the mapping of the arcsin is impressive. I learn alot from your videos but cant understand everything cuz I'm a mechanical engineer preparing my masters thesis. thank you very much 😊
I just finished calc1 , yes im the most junior here but i still try to understand ur videos with my limited knowledge, (i luv calc) Thank you for making such nice videos❤. If possible Sir could u make a video on Feynmans technique for beginners, like how does it work even .
He has a whole playlist of using the Feynman technique I would recommend checking out, you’ll pick it up fast as it’s a pretty straightforward concept. If you’re good with calculus it will feel super 👌
@@maths_505 In German math texts we also tend to prefer phi as the argument variable of the trigonometric functions, for no particular reason. alpha is also very common. 😃
@@aniritri8635 no if you look at the graph y = x and y = ln(x) there is no intersection. Similarly, in the complex plane, if you look at the domain colour map for w = z and w = ln(z) there is no common areas of colour
@@Daniel-yc2ur i see, i only started learning about complex number a few days ago, heard that they can solve any equation so decided to ask. Thanks for the info will check what those terms mean
ERROR CORRECTION: at the 8:35 mark, that should be sqrt(1-w^2).

Write sin(x) as the imaginary part of e^(ix) and then use either the Laplace transform or the melin transform.
Watching your videos after a long time(Exams occupied me), and as usual the video was a banger.
Thanks mate

You ain't junior bro , i'm here with you
Why phi?? You’d use theta or x as the variable usually, otherwise good, cool video as usual.
I just like phi more

Can you do ln(x) = x ?
No solution.
@@maths_505 even in the complex plane ?

Damn second😊
