Answer: Using the trigonometric definitions for any angle theta​, the trigonometric functions that are undefined when x = 0 are​ tanθ and secθ. The trigonometric functions that are undefined when y = 0 are cotθ and​ cscθ. The trigonometric functions that do not depend on the value of r are​ tanθ and​ cotθ.

Step-by-step explanation:

Construct a trigonometric ratio for triangle and you will see that cot and tan are independent of the value, r.

NOTE: A ratio is undefined if the denominator is zero.

Also, from that trigonometric ratio constructed, if x=0, only tanθ and secθ become undefined. And if y=0, only cotθ and cscθ become undefined.

The attachment below shows a constructed trigonometric ratio.

Which of the coordinates listed below could represent a point found on the line 3x?
Kamila [148]
Well.. You seem to have forgotten to add the coordinates...

Anyway, the line is represented by the function f(x) = 3x .

Any point which follows the form (x,3x) will be on the line

for example (-3,-9) ; (-2,-6) ; (-1,-3) ; (0,0) ; (0.333333,1) ; (1, 3) ; (2,6) ; (3,9) ; and so on....

15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
romanna [79]

Answer:

x = 14 and 2/3

Step-by-step explanation:

Make an equation where x is the number.

2x - 15 = 7 + 1/2x

Then, solve the equation.

multiply both sides by 2 to get rid of the fraction

4x - 30 = 14 + x

subtract x from both sides

3x - 30 = 14

add 30 to both sides

3x = 44

divide both sides by 3

x = 14 and 2/3
