cos(x)

sin(x)

tan(x)

cot(x) (correct)

Which of the following is NOT a trigonometric identity?

sin(2x) = 2sin(x)cos(x)

sin^2(x) + cos^2(x) = 1

cos(2x) = 2cos^2(x) - 1 (correct)

tan(x) = sin(x)/cos(x)

Which of the following is NOT a Pythagorean identity?

cot^2(x) + 1 = csc^2(x)

sin(x) + cos(x) = 1 (correct)

1 + tan^2(x) = sec^2(x)

sin^2(x) + cos^2(x) = 1
