Differentiate the following functions with respect to x.

Step-by-step explanation:

Step(i):-

Given function

                  ....(i)

we will use differentiation formulas

i) y = cos h⁻¹ (x)

   Derivative of cos h⁻¹ (x)

ii)

      y = sec h⁻¹ (x)

   Derivative of sec h⁻¹ (x)

Apply U V formula

Step(ii):-

Differentiating equation (i) with respective to 'x'
