Given
, (1, 1) to find the tangent line equation.
let
so,
so let's find
on applying the exponent rule we get,
so ,
so,
let
so ,
=
=
=
=>
now let us find f'(x) value at (1,1) which is slope
f'(1) =
=
now , the slope of the tangent line is
we have the solope and the points so the equation of the tangent line is
=
but
so,
=
=
so ,
is the tangent equation
