The Newton-Raphson method is a numerical method used to find the roots of an equation, i.e., the values of x that make the equation equal to zero. It is a powerful tool for solving complex non-linear equations, and it can be implemented in Excel using a combination of the “Goal Seek” function and a user-defined function.

The Newton-Raphson method is based on the idea of iteratively improving an estimate of the root, based on the tangent line to the curve of the equation at the current estimate. The method starts with an initial guess for the root, and then calculates a new estimate.

Follow the steps below to learn how to use Newton Raphson Method in Excel.

Entropy is a measure of disorder in a system. The higher the entropy, the more disordered the system. Entropy change is the difference between the entropy of the initial state and the entropy of the final state.

The entropy change formula is (x_ij*log₂ (x_ij)). To calculate the entropy change in Excel follow the steps below.

The Linest function helps you figure out statistics for a single line in your data. It does this by using something called “least squares” to find a straight line that matches your data closely.

Then, it gives you a set of numbers that describe that line. It does all this by taking data you put into the Linest formula and giving you back the results in an array.

Excel provides several cube functions that you can use to aggregate and analyze data stored in OLAP (Online Analytical Processing) cubes, which are multi-dimensional data structures used for data analysis. Cube functions allow Excel to access data from an Analysis Services data source without using a Pivot Table.
