 Question : If the given function is continuous and having a root in [-1, a] where

a= (last three digits of registration no as 1.23) 

    f(x)=e^x  cos⁡x

(i)                  Find the root using a bracketing (bisection/false position) method.                                    

(ii)                Find the root using an iterative (newton Raphson/fixed point) method.                           

Answer:
