In Google Sheets, the function SEC is a trigonometric function used to calculate the secant of an angle.

Here's how the SEC function works:

The "angle" parameter is the angle in radians for which you want to calculate the secant. The secant of an angle is the reciprocal of the cosine of that angle. Mathematically, sec(x) = 1/cos(x).

For example, if you want to calculate the secant of an angle that is 45 degrees (π/4 radians), you can use the formula =SEC(PI()/4). The PI() function returns the value of π, which is approximately 3.14159. The function will calculate the secant of the angle and return the result.

The SEC function is commonly used in trigonometry and mathematical calculations involving angles and ratios. It can be useful when working with data that involves periodic or cyclical patterns.
