Question

Use Newton's raphson method to solve equation 3x-cosx-1=0

Answer 1

Hi,

The given function is 3x-cosx-1=0.

We have to solve it by using Newton-Raphson Method.

This method is used to find a root of an equation.

⇒ In this method, we use the sequence of x-intercepts to approximate a root of the given equation.

So here we have

f (x) = 3 x - cos x - 1

f' (x) = 3 ( 1 ) - ( - sin x ) - 0

f' ( x ) = 3 + sin x
