Practice problem
Which of the following statements about the sine function are true?
The sine function is even.
sin(2x)=2sin(x)\sin(2x) = 2\sin(x)sin(2x)=2sin(x)
sin(x+π)=−sin(x)\sin(x + \pi) = -\sin(x)sin(x+π)=−sin(x)
The sine function is odd.
The domain of the sine function is [0,2π)[0, 2\pi)[0,2π).
The range of the sine function is [−1,1][-1, 1][−1,1].
Type a concept, like “slope” or “photosynthesis”.
