How to Derive Answers Using N Formula

[DYLAN4321]

Hi,

I have been given the attachment formula and asked to enter this into an excel spreadsheet. Although I am not entirely sure how the answer was derived. Is anyone able to explain step by step as I want to try and enter this into an excel spreadsheet. For reference N = Newtons

I believe you were suggested to look up a solution method, the Newton-Raphson approximation being one method mentioned. Do you have a solution method you would like to use? Excel will not simply solve it for you.

There is no "N" in the given equation so there can be no "N" in the answer! Have you left something out?

I have been given the attachment formula and asked to enter this into an excel spreadsheet.

It is not clear what your Excel formula is supposed to compute: \(\displaystyle \frac{7134611197}{T_2^2}-T_2\) for the given value of $T_2$, the value of $T_2$ for the given left-hand side of this equation or something else. Also, for $T_2=956$ we have \(\displaystyle \frac{7134611197}{T_2^2}-T_2\approx6850\) and not $6863$.

I believe you were suggested to look up a solution method, the Newton-Raphson approximation being one method mentioned.

Mentioned where? This is a quadratic equation in $T_2$.

There is no "N" in the given equation

N is the units in which $T_2$ is measured.

The OP also posted this on another site. Sorry, I should have included the link to it.
