from Ekeeda Hello friends in this video
we are going to start how to find the
derivative of a constant function using
first principle so let us start so I am
going to take a function y is equal to f
of X which is going to be a constant
function so we'll start with let f of X
is equal to constant function P now to
find the derivative of the first using
the first principle they are going to
use the formula that limit X tending to
0 f dash X is equal to limit H tending
to 0 f of X plus h minus f of X upon H
right so we have taken a function that
is constant now in this formula we have
two terms f of x plus h and f of X now
we are going to find the second term
that is f of X plus h so let us start f
of X was equal to K then we'll go for f
of X plus h to find f of X plus h we are
going to replace X by X plus h so since
we don't have any X in this function
will write K only let us substitute
these two values in the formula so f
dash X is equal to limit X tending to 0
f of X plus h we have K minus again f of
X we have K upon H so K minus K will
give you 0 so limit X tending to 0 K
minus K is 0 upon H so 0 upon H will
give you 0 and the derivative of this
function will be 0 so remember friends
derivative of any constant from
is equal to zero I hope you have
understood this video thank you for
watching this video stay tuned with Iggy
ah and subscribe Ikeda
you
