I need to find the table of -csc theta

AVprozaik [17]

See below for the table of -csc theta

<h3>How to determine the table?</h3>

The function is given as:

-csc theta

Rewrite properly as:

$-\csc(\theta)$

This is calculated as:

$-\csc(\theta) = -\frac{1}{\sin(\theta)}$

Set $\theta$ to 0, 30, 45, 60 and 90

$-\csc(0) = unde fined$

$-\csc(30) = -2$

$-\csc(45) = -\sqrt 2$

$-\csc(60) = -\frac{2\sqrt 3}{3}$

$-\csc(90) = -1$

So, the table of -csc theta is

Angle -csc theta

0 undefined

30 -2

45 -√2

60 -2/3 √3

90 -1

Trigonometry

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify

a = 12

b = 5

c = x

Step 2: Solve for x

Substitute in variables [PT]: 12² + 5² = x²
Evaluate exponents: 144 + 25 = x²
Add: 169 = x²
[Equality] Square root both sides: ±13 = x
Rewrite: x = ±13

Since we are dealing with positive numbers, we can disregard the negative root.

∴ x = 13
