Front

What is the definition of secant (sec) in trigonometry?

Back

Secant is the reciprocal of cosine: sec(x) = 1/cos(x).

Front

What is the Pythagorean identity involving secant?

Back

The Pythagorean identity is: sec²(x) = 1 + tan²(x).

Front

Simplify: sec²(x) - 1

Back

tan²(x).

Front

What is the relationship between tangent and cotangent?

Back

tan(x) = 1/cot(x) and cot(x) = 1/tan(x).

Front

What is the definition of tangent (tan) in trigonometry?

Back

Tangent is the ratio of sine to cosine: tan(x) = sin(x)/cos(x).

Front

What is the definition of cotangent (cot) in trigonometry?

Back

Cotangent is the reciprocal of tangent: cot(x) = 1/tan(x).

Front

Simplify: tan(x) * cot(x)

Back

1.

Front

What is the definition of sine (sin) in trigonometry?

Back

Sine is the ratio of the opposite side to the hypotenuse in a right triangle: sin(x) = opposite/hypotenuse.

Front

What is the definition of cosine (cos) in trigonometry?

Back

Cosine is the ratio of the adjacent side to the hypotenuse in a right triangle: cos(x) = adjacent/hypotenuse.

Front

What is the Pythagorean identity involving sine and cosine?

Back

sin²(x) + cos²(x) = 1.
