Determine whether each statement is true or false. If false, tell why. csc 22° ≤ csc 68°

Determine whether each statement is true or false. See Example 4. tan 28° ≤ tan 40°

Determine whether each statement is true or false. See Example 4. cos 28° < sin 28° (Hint: sin 28° = cos 62°)

Determine whether each statement is true or false. See Example 4. cot 30° < tan 40°

Give the exact value of each expression. See Example 5. tan 30°

Give the exact value of each expression. See Example 5. sin 30°

Each figure shows an angle θ in standard position with its terminal side intersecting the unit circle. Evaluate the six circular function values of θ.

Use the formula ω = θ/t to find the value of the missing variable.

ω = 2π/3 radians per sec, t = 3 sec
