## What does the secant line represent?

A secant line, also simply called a secant, is a line passing through two points of a curve. In geometry, a secant line commonly refers to a line that intersects a circle at exactly two points (Rhoad et al. 1984, p. 429).

### What is the slope of the secant line through the points?

The slope of the secant line is also referred to as the average rate of change of f over the interval [x,x+Δx].

#### Which angles are formed by two secant lines?

If two lines intersect outside a circle , then the measure of an angle formed by the two lines is one half the positive difference of the measures of the intercepted arcs . In the circle, the two lines ↔AC and ↔AE intersect outside the circle at the point A .

**How to calculate the secant?**

How to calculate secant First, you need to determine what information is available to you. The next step is to plug these values into the above equation so sec x = 5/4 = 1.25. The last step would be to use the actual angle to check this. To do this you would simply need to enter the angle into the formula 1/cosx. Analyze the results.

**What is the difference between secant and cosine?**

As nouns the difference between secant and cosine is that secant is (geometry) a straight line that intersects a curve at two or more points while cosine is (trigonometry) in a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse symbol: cos.

## What is secant the inverse of?

The secant is the inverse of the cosine. The reciprocal of the abscissa of the endpoint of an arc of a unit circle centered at the origin of a Cartesian coordinate system, the arc being of length x and measured counterclockwise from the point (1, 0) if x is positive or clockwise if x is negative.

### Is secant 1 over cosine?

Let’s recall that secant is 1 over cosine theta and so it inherits a lot of properties from cosine theta. For example cosine theta is even so is secant and it’s easy to show that. Secant of negative theta is 1 over cosine of negative theta and that’s of course cosine theta.
