Hello friends now we see the new chapter
that derivative under derivative first
of all we see the subtopic one right
derivative of a function at any point
let F X be a function and small 'a' be a
point in its domain
if lipid H tends to 0 F of a plus h
minus F a whole thing divided by H
exists then it is called derivative of
FX with respect to X at Point a
and it is denoted by f dash a therefore
a brush a is equal to limit X tends to 0
f of T plus h minus f of a whole thing
divided by H in general we write F rash
X is equal to limit H tends to 0 f of X
plus h minus f x whole thing divided by
H this is known as first principle of
derivative
so this is all about derivative of a
function at any point thank you
