The term “secx” stands for the secant of the angle x, which is a trigonometric function. The secant can be defined in two different ways:
1. Reciprocal of the cosine: The secant of an angle x is equal to the reciprocal of the cosine of x. Mathematically, it can be expressed as:
sec(x) = 1 / cos(x)
This definition is valid for all values of x except when the cosine of x is equal to zero, which results in an undefined value for sec(x).
2. Ratio of hypotenuse to adjacent side: The secant of an angle x in a right triangle is equal to the ratio of the length of the hypotenuse to the length of the adjacent side. Mathematically, it can be expressed as:
sec(x) = hypotenuse / adjacent side
This definition is valid only for acute angles in a right triangle.
In both cases, the secant function is used to evaluate the relationship between the sides of a right triangle or to find the lengths of these sides given certain angle measurements. It is also used in various branches of mathematics and physics, such as trigonometry, calculus, and engineering.
