Which of the following are reciprocal functions? sin x and cos x tan x and cot x cot x and csc x csc x and sec x

1). sin x  and csc x

2). cos x and sec x

3).tan x and cot x

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

Csc θ = Hypotenuse /Opposite side

Sec θ = Hypotenuse /Adjacent side

Cot θ = Adjacent side/Opposite side

To find the correct answers

From the above points we get reciprocal of functions are,

1). sin x  and csc x

2). cos x and sec x

3).tan x and cotx

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
