EXAMPLE 3.7SBTEB 2003, SBTEB 2006, SBTEB 2010, saTEFind the derivative of sin z using first principal.

Answer»

I didn't understand first principal explain plz

Derivative by first principlerefers to using algebra to find a general expression for the slope of a curve. It is also known as the delta method. The derivative is a measure of the instantaneous rate of change, which is equal to

This expression is the foundation for the rest of differential calculus: every rule, identity, and fact, follows from this.

expression is which I have used in solving question

and what a function denote foe

what is use of h and x

which function.......

x is variable and h is limit for which we are solving

yes

thnx

what is limit

limit is h tending to zero

can u differentiate sin x by your method or easy and simple way
