Bisection method Calculator

Calculates the root of the given equation f(x)=0 using Bisection method.

Select a and b such that f(a) and f(b) have opposite signs. The convergence to the root is slow, but is assured.
This method is suitable for finding the initial values of the Newton and Halley’s methods.

    i put 2xcos2x +(x+1)^2=0 solve by bisection method [-3,-2] it is not taking
    from Keisan
    Please input the formula as below.

    2*x*cos(2*x)+(x+1)^2

    i have put a function √x-cos⁡x and value of a and b (0,1) but still iam unable to get the solution
    from Keisan
    Please input
    "sqrt(x)-cos(x)" in
    f(x).

    how to designate the superscript like as if we have 3.61111×10−8T 3 − 6.95238×10−5T 2 + 0.0805437T − 0.3 =0 if we have such kind of questions in Bisection method
