Differentiate || f(x)=2x² || by First principle || Calculus || 

That's good sir. I like how you explain everything step at a time 🎉

This was very helpful sir, I've subscribed, liked and left this Comment thank so much.

Thank you sir ❤

Nice hand writing 🤞🤞🤗✍️

Sir where is the 2hx coming from ,coz you said we simplify 🤔🤔

That was good sir. But it's my first time to such a method. So it's a little bit hard for me to understand it.

Still lost on the 2(x²+2hx+h²)
