What is the relationship between sin(x) and cos(x)?
sin(x) and cos(x) are always equal to each other.
sin(x) is the derivative of cos(x).
cos(x) is the inverse of sin(x).
sin(x) and cos(x) are related through the identity sin^2(x) + cos^2(x) = 1.
If sin(x) = 0, what are the possible values of x?
x = 2nπ, where n is an integer
x = nπ/2, where n is an integer
x = n/2, where n is an integer
x = nπ, where n is an integer
What is the range of the cosine function?
[1, 3]
[-2, 2]
[0, 2]
[-1, 1]
How do you express tan(x) in terms of sin(x) and cos(x)?
tan(x) = cos(x) / sin(x)
tan(x) = sin(x) + cos(x)
tan(x) = sin(x) - cos(x)
tan(x) = sin(x) / cos(x)
