Derivative of xsinx from first principles

In this video, I showed how to find the derivative of xsinx from first principles. This process involves the use of the angle sum identity and other limit identities in relation to sine and cosine as the argument approaches zero.

Thank you so much sir firstly I am an Indian and thought no it's in English I won't be able to understand it properly but your steps were super clear and explainatio was so easy thankyou so much sir 😊💗

So simplified thank you very much. May God bless you always

... A good day to you Newton, A great presentation my friend; keep that little piece of chalk moving! Now I understand how you keep your algebraic skills in top shape, just by applying First Principles regularly, and not always choosing the existing short cuts, that make a person "math" lazy in the long run (lol) ... Thank you again Newton for your great math efforts, Jan-W

Hello Prime Newton, good day. Awesome tutoring. Please can you help with this Differentiation from the First Principle Question: Y = Sin(2x)/2x-5

[@PrimeNewtons]

lim [Sin2(x+h)/2(x+h)-5] - [sin2x/(2x-5)]. Do the algebra and trig as h goes to 0

@@PrimeNewtons pls can you send me your email. I would love to send you my solving.🙏

[@kingsleychukwuekwu8194]

@@PrimeNewtons can I solve the numerator and denominator separately since it's not undefined: i.e neither numerator nor denominator equates to zero

Tq sir for your explaination ❤️

Hi Mr. Prime Newtons. May I know how do you derive limit of sinx/x is 1? Is it a given formula? I was confused by how to solve for xsinx. limits of (cos (h) - 1)/h + xcosx. limits of (sin (h))/h to obtain solution 😅

I made videos on this channel explaining them. Please go to my channel homepage and type in the search keywords. You will find any video
