Check the picture below.

the hole on te red one, means that endpoint is not included in it, namely x = 1 is not part of it, namely x > 1, anything greater BUT not equals to "x".

likewise, the solid circle on the blue one means, that endpoint is included, namely x ⩽ 1, anything lesser than 1, including the x = 1 itself, so x = 1, x = 0, x = -1, x = -2.....

The measure of an angle in standard position is given. Find two positive angles and two negative angles that are coterminal with
devlian [24]

Answer:

13π/4 , 21π/4, -3π/4, -11π/4

Step-by-step explanation:

Coterminal Angles are angles which share the same initial side and terminal sides.

To find coterminal angles, simply add or subtract 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.

5π/4 =(4π/4)+(π/4)

Our Angle 5π/4 is in the 3rd quadrant and exceeds π radians by (π/4) radians, or 45° angular measure.

The 2 positive co-terminal angles would be:

Adding 2π

5π/4 + 2π = 13π/4

Adding another 2π

5π/4 + 2π +2π = 21π/4

The two negative co-terminal angles would be:

Subtracting 2π

5π/4 - 2π = -3π/4

Subtracting another 2π

5π/4 - 2π -2π = -11π/4

The coterminal angles are:

13π/4 , 21π/4, -3π/4, -11π/4

zavuch27 [327]

Multiply each term in the first set of parentheses by each term in the second set, then combine like terms.

7x x 3x^2 = 21x^3

7x x -4x = -28x^2

7x x 5 + 35x

-6 x 3x^2 = -18x ^2

-6 x -4x = 24x

-6 x 5 = -30

Combine like terms to get:

21x^3 - 46x^2 + 59x - 30
