AP Precalc (Unit 3 Practice Test Questions)

Front

Factor the equation: 0 = sin^2(x) - sin(x)

Back

0 = sin(x)(sin(x) - 1)

Front

In which quadrants is cos(θ) positive?

Back

cos(θ) is positive in the 1st and 4th quadrants.

Front

What is the identity for 1 + cot^2(x)?

Back

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

Front

What is the exact value of tan(π/4)?

Back

tan(π/4) = 1

Front

Simplify the expression: (tan(x) * cot(x)) / csc(x)

Back

(tan(x) * cot(x)) / csc(x) = sin(x)

Front

What is the Pythagorean identity involving sin and cos?

Back

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

Front

What is the value of sin(π/2)?

Back

sin(π/2) = 1

Front

What is the value of cos(0)?

Back

cos(0) = 1

Front

What is the relationship between sin(x) and csc(x)?

Back

csc(x) = 1/sin(x) and is undefined when sin(x) = 0.

Front

What is the value of tan(0)?

Back

tan(0) = 0
