for example, is type =TRIM, then click on the Enter key. Drag the formula to all cells, and watch as the standard output is shown rather than scientific notation. We use the CONCATENATE function ...

This example and notation are taken from Bard (1974). A two-equation model is used to fit U.S. production ... The following code computes the logarithm of the likelihood function: /* 2. Compute Sigma ...

The equation of a straight line can also be written in the form \(f(x) = mx + c\). This is called function notation and is just another way of expressing the relationship between two variables.

(x)\). To find an inverse function, form an equation by giving the output value a name using a letter (such as \(y\)), then rearrange the equation to make \(x\) the subject.
