Working on a maths assignment and we're trying to use Excel for a bisection method.
$$\frac12 e^{x/2}+\frac{1}{2x}-\frac32=0$$
Here is a pic, I can't get the formula to work with the exponent.
This is what we've done so far, can anyone spot what we've got wrong with the formula?
It should read (1/(2*A8)) For the second term
Your current second term reads (1/2 *A8) which means $\frac{1}{ 2} A8$
