Which trigonometric functions are equivalent to sin (theta)? Select all that apply.(2 correct answers)

a.) sin(-theta)
b.) sin(theta +2pi)
c.) -sin(theta)
d.) -sin(-theta)
e.) sin(theta + pi/2)

sin(θ) = sin(θ + 2π) = -sin(-θ)

b and d

This can be shown by substituting a value for θ

sin(π ÷ 3) = 1/2

sin(π ÷ 3 + 2π) = 1/2

-sin(π ÷ 3) = -1/2

-sin(-π ÷ 3) = 1/2

sin(π ÷ 3 + π ÷ 2) = √3/2

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
