Front

What is the Pythagorean identity for sine and cosine?

Back

sin²x + cos²x = 1

Front

What is the definition of secant (sec)?

Back

sec x = 1/cos x

Front

What is the definition of cosecant (csc)?

Back

csc x = 1/sin x

Front

What is the definition of tangent (tan)?

Back

tan x = sin x / cos x

Front

What is the definition of cotangent (cot)?

Back

cot x = 1/tan x = cos x / sin x

Front

What is the relationship between secant and tangent?

Back

sec²x = 1 + tan²x

Front
