In this task, a simple implementation of the bisection method for finding roots of continuous functions is to be developed. Let f: a b Real numbers be a continuous function with a b and fafb According to the intermediate value theorem, f has at least one root in a b The bisection method works as follows: Set L a R b If the condition fL fR is not met, terminate. Otherwise: Test whether R L TOL, where TOL is user tolerance eg TOL If yes, there is a root in L R; otherwise, Continue with subintervals LLR and LR R following step Write a recursive function void bisectdouble L double R double TOL implementing the bisection method, and a double function fdouble x returning fx Test your implementation with various functions and intervals, outputting the intervals containing roots and the function values at the midpoint. For instance, running with fx xxx and L R might produce output like: "A root of f lies in ee fLRe For fx sinx you might get output similar to: "A root of f lies in ee fLRe "A root of f lies in ee fLRe "A root of f lies in ee fLRe

The bisection method works as follows:
Set L a R b
If the condition fL fR is not met, terminate. Otherwise:
Test whether R L TOL, where TOL is user tolerance eg TOL If yes, there is a root in L R; otherwise,
Continue with subintervals LLR and LR R following step
Write a recursive function
void bisectdouble L double R double TOL
implementing the bisection method, and a double function fdouble x returning fx
Test your implementation with various functions and intervals, outputting the intervals containing roots and the function values at the midpoint.
For instance, running with fx xxx and L R might produce output like:
"A root of f lies in ee fLRe
For fx sinx you might get output similar to:
"A root of f lies in ee fLRe
"A root of f lies in ee fLRe
"A root of f lies in ee fLRe
