A squareroot of fx ex 2x2 lies in the interval 1 2 Determi
A squareroot of f(x) = e^x - 2x^2 lies in the interval (1, 2). Determine this squareroot with the Newton-Raphson method to five decimal accuracy.
Solution
Here we take the formula of Newton raphson method
Xn+1=xn-f(xn)/f\'(xn)
Then it will be x=1
X1=1
X2=2
X3=2.5
X4=2.55 something
X5=2.7....... and
X1=2
X1=2
X2=2.5
X3=2.7....
X4=2.75....
X5=2.8......
The above formula by root of f(x)=ex-2x2 with the intervals (1,2)
are following by the method the decimals are formed.
