Explain why domain restrictions for inverse trigonometric functions are necessary

Mathematics
1 answer:
lakkis [162]3 years ago
8 0

Step-by-step explanation:

Remember that any function pairs each <em>x</em> value with <u>exactly one</u> <em>y</em> value.  No <em>x</em> can have more than one <em>y</em> corresponding to it.

Example: when you take the points on the function y = sin x and reverse their coordinates (switch the <em>x</em>'s and <em>y</em>'s), you get the blue squiggly line (see graph) that goes up and down the <em>y</em>-axis.  For instance, a point on the graph of y = sin x is (pi/2, 1) and this becomes the point (1, pi/2) on the blue wave.

The blue wave is <u>not</u> a function!  It fails the Vertical Line Test miserably. Each <em>x</em> corresponds to an infinite number of <em>y</em>'s.

Going back to y = sin x, you restrict its domain (all real numbers) to a set of numbers that will prevent the inverse from "doubling back" on itself--each <em>x</em> will correspond to only one <em>y</em>.

There are standard ways of doing this for each trigonometric function.  For the sine function, you restrict its domain to the interval [-pi/2, pi/2}.  When the coordinates of the restricted graph are switched, you get the red graph, which is a function, the inverse sine function.

1.A cube has side lengths of 15 inches, what is the surface area and volume of the cube? 2. A cube has side lengths of 8 inches,
omeli [17]

Answer:

Cube 1: 3375 cubed inches, 1350 inches squared.

Cube 2: 512 cubed inches, 384 inches squared.

Step-by-step explanation:

Formula for Volume of a Cube:  V=s^3\\ (s - side length)

Formula for Surface Area of a Cube: SA=6s^2 (s- side length)

<h3>For Cube 1:</h3>

The side length's 15 inches.

Find the volume:

V=15^3\\\rightarrow 15*15*15=3375\\\boxed {V=3375}

The volume of cube one is 3375in³.

Find the surface area:

SA=6(15)^2\\\rightarrow 15^2 = 225\\SA = 6 * 225\\\boxed {SA=1350}

The surface area of cube 1 is 1350in².

<h3>For Cube 2:</h3>

The side length's 8 inches.

Find the volume:

V=8^3\\\rightarrow 8*8*8= 512\\\boxed {V=512}

The volume of cube two is 512in³.

Find the surface area:

SA=6(8)^2\\\rightarrow 8^2=64\\SA=6*64\\\boxed {SA=384}

The surface area of cube 2 is 384in².
