the change in x is 1 and 2 in y respectively

the points are in order from r (x,y) to m (9,8) to s (10,10

if we take - 1 from x and 2 from y we will get r, or (8,6)

By using <em>algebra</em> properties and <em>trigonometric</em> formulas we find that the <em>trigonometric</em> expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equivalent to the <em>trigonometric</em> expression $\frac{2\cdot \tan x}{\cos x}$ .

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>

In this question we have <em>trigonometric</em> expression whose equivalence to another expression has to be proved by using <em>algebra</em> properties and <em>trigonometric</em> formulas, including the <em>fundamental trigonometric</em> formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:

$\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ Given.

$\frac{1 + \sin x - 1 + \sin x}{1 - \sin^{2}x}$ Subtraction between fractions with different denominator / (- 1) · a = - a.

$\frac{2\cdot \sin x}{\cos^{2}x}$ Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)

$\frac{2\cdot \tan x}{\cos x}$ Definition of tangent / Result

By using <em>algebra</em> properties and <em>trigonometric</em> formulas we conclude that the <em>trigonometric</em> expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equal to the <em>trigonometric</em> expression $\frac{2\cdot \tan x}{\cos x}$ . Hence, the former expression is equivalent to the latter one.

Select all the equations that represent functions where the range decreases as the domain increases.

A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
