Using calculator

Perform calculations of bisection method with calculator:

1. Use table to find $x_0$ for $f\left(x\right)<0$ and $x_1$ for $f\left(x\right)>0$: MENU > 9 > f(x) = <equation> > Set appropriate range
2. Open spreadsheet: MENU > 8
3. Fill A1 with $x_0$ and B1 with $x_1$
4. Fill C1 with the average of A1 and B1. You should use formula: OPTN > 1 > (A1+B1)/2
5. Fill D1 by evaluating f(C1)
6. For E1, produce $0$ if D1 $<0$ and produce 1 if D1 $\text{[PARSE ERROR: Undefined("Command("ge")")]}0$: ((D1/Abs(D1))+1)/2
7. For A2, produce C1 if E1 is $0$, otherwise produce $A1$: (1-E1)C1+E1A1
8. For B2, produce C1 if E1 is 1, otherwise produce B1: E1C1+(1-E1)B1

Note: For step 4, 6, 7, and 8, consider providing an appropriate range as well. E.g., up-to 13th row. Note 2: To view values of arbitrary significant digits, update Number Format to Fix, and Spreadsheet > Show Cell to Value.
