Back

csc(x) is equivalent to 1/sin(x).

Front

What is the value of cos(x) in terms of sine?

Back

cos(x) = sqrt(1 - sin^2(x)).

Front

What does the Pythagorean identity sec^2(x) represent?

Back

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

Front

What is the quotient identity for tan(x)?

Back

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

Front

What is the result of csc^2(x) - cot^2(x)?

Back

csc^2(x) - cot^2(x) = 1.
