Answer:
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
