    iterative formula is x= tan^−1(x) + π x0=3/2 π x1=tan^−1(3/2 π) + π = 4.503 x2=tan^−1(4.503) + π=4.494 x3=tan^−1(4.494) + π = 4.493 x4=tan^−1(4.493) + π = 4.493 hence , x=4.493

    x0 is π + 2π/2 = 3/2 π
  20. G

    Mathematics: Post your doubts here!

    Find x0 by => π + 2π/2 as from the diagram u can see root is between π and 2π. then put the value in the given iterative formula and continue until u get the right value.Hope that helped !
