Trigonometric Ratios and Conversions Quiz

Sine of 90 degrees is the maximum value of 1.

Reciprocal of secant of 30 degrees is 2.

Tangent of 45 degrees is 1.

Secant is the reciprocal of cosine, so if cos(θ) = 0.6, sec(θ) = 1/0.6 = 1.2.

Sine of 180 degrees is 0.

If sec(θ) = 2, then cos(θ) = 1/sec(θ) = 1/2.

Cosine of 0 degrees is 1.

Cosecant is the reciprocal of sine, so if sin(θ) = 3/5, csc(θ) = 1/sin(θ) = 5/3.

Tangent of 0 degrees is 0.

If csc(θ) = 2, then sin(θ) = 1/csc(θ) = 1/2.

Cosine of π/6 is equivalent to sine of π/6.

Given sin(θ) = 0.8, cos(θ) is its complementary value of 0.4.

Cotangent of π/4 is equivalent to the square root of 2.

Given tan(θ) = 4/3, you can find cos(θ) using the Pythagorean identity.

Sine of π/4 is equivalent to sine of π/6.

Given tan(θ) = -3/4, you can find sin(θ) using the Pythagorean identity.

Tangent of π/3 is equivalent to cosine of π/3.

Given cot(θ) = 5/4, you can find sec(θ) using the Pythagorean identity.

Cosine of π/4 is equivalent to cosine of π/6.

Given sec(θ) = -5/4, you can find cos(θ) using the reciprocal.

The amplitude of cosine function is the coefficient outside the function, which is 3.

The amplitude of sine function is the coefficient outside the function, which is 2.
