You see tan (theta)=0 for theta=0. So, when the angle is very small almost approaching 0 degree, we can write theta = tan(theta). In the video, the deformation of the fluid element due to the upper layer of fluid shown as d(beta) is a very small differential angle so we can represent it as tan (beta). I hope it gets clear now.
What software do u use?
I use Microsoft Powerpoint to make animations
Outstanding explanation sir
Thank you very much for the appreciation
What a great video, cheers from Argentina!!!

Really helpful
Thanks for the appreciation. Do it share it with your friends and subscribe my channel for more such videos.
great explanation, from north Syria thanks alot❣️
Glad it was helpful for you.
Sir, can you please explain how uncertainty for the dynamic viscometer will be measured?
Why is d(Beta)=tan(Beta)?
