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

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)
