            1)
            2)
            3)
            4)
            5)
            6)

Example:
            Differentiate with respect to 'x'.
Solution:
            Let
            Diff: w.r.t 'x'
             
            
               
               
               

               

 Example:
            If , then show that
               
Solution:
                We have
             ——————— (1)
                Squaring both sides
            
                          using (1)
Diff: w.r.t 'x'
