If I have the equation of X raised to the power of X is Y, how do I calculate X if I am given Y? This can't be done using elementary functions. You can use the Lambert W function to solve y=xxy=xx. Take the natural log of both sides, then replace xx with xln...
You could use MS Excel to find the equation. Enter the points in cells as shown, and get Excel to graph it using "X-Y scatter plot". This gives the black curve shown. Then right click on the curve and choose "Add trendline" Choose "Polynomial" and "Order 2". (This gives ...
or you can use a manual sample size calculation if you want to test your math skills. Cochran’s formula is perhaps the most well known equation for calculating sample size, and widely used when the population is large or unknown.
Watts are SI (metric) units for power, and calculating power usually isn't difficult. There are two ways to do it, though, depending on whether you're talking about mechanical or electrical power. The watts equation for an electrical circuit takes into account the voltage across the circuit ...
To solve an equation using Excel Solver, you can follow the above-mentioned steps. However, to use this add-in, you need to install it first. Following that, you can use and apply it to your Excel spreadsheet. Read:Microsoft Power Query for Excel helps with data discovery ...
Excel’s POWER function is a surprisingly simple and easy to use function. On its own, it can easily perform basic mathematical exponential calculations. When nested inside a complex mathematical equation, however, the POWER function can reduce the size of otherwise very complex formulas. ...
functions where one of the x variables is squared, or taken to the second power like this: **x2**. When these functions are graphed, they create a parabola which looks like a curved "U" shape on the graph. This is why a quadratic equation is sometimes called aparabolaequation. ...
Step 1: Insert the power rule into the limit definition: Step 2: Use the binomial theorem to evaluate the equation from Step 1: Note: I included “…” to indicate this is an incomplete series. In order to prove the power rule you don’t need to write out the entire series. Step 3...
The Bain study noted that identifying the sweet spot of customer segmentation is “only half of the growth equation.” The next essential step for every company planning to act on market segmentation is to take an “unflinching inventory” of internal capabilities—both strengths and weaknesses. ...
The moving average convergence divergence is a technical indicator used to assess the power of price movement in a market.
