Understanding the Expression sec x + c: What It Represents & How It Works

sec x + c

The expression “sec x + c” represents the sum of the secant of x and the constant c

The expression “sec x + c” represents the sum of the secant of x and the constant c.

To better understand this expression, let’s break it down:

1. Secant of x: The secant function (abbreviated as sec) is defined as the reciprocal of the cosine function. It is denoted by sec x or secant x. Mathematically, sec x = 1 / cos x. The secant function returns the ratio of the hypotenuse to the adjacent side in a right triangle with an angle x.

2. Constant c: The constant c represents any numerical value that does not change. It can be positive, negative, or zero.

Therefore, the expression sec x + c represents the sum of the secant of x and the constant c. It is important to note that when you add a constant to a function, such as sec x, it only shifts the graph vertically, without altering the shape of the graph.
