✍️ Sample PRE CALCULUS Questions & Answers

1. In which quadrant is the angle 210° located, and what is the sign of its tangent?
Quadrant III, positive

210° is in Quadrant III where both sine and cosine are negative, making tangent positive.

2. Using De Moivre's Theorem, what is [2(cos 30° + i sin 30°)]³?
8(cos 90° + i sin 90°)

By De Moivre's Theorem, r^n(cos nθ + i sin nθ) = 2³(cos 90° + i sin 90°) = 8(cos 90° + i sin 90°) = 8i.

3. If two chords intersect inside a circle and the segments of one chord are 3 and 8, while one segment of the other chord is 4, what is the remaining segment?
6

By the intersecting chords theorem: 3 × 8 = 4 × x, so x = 6.

4. For the equation 2sin(x) - 1 = 0 on [0, 2π), the solutions are:
π/6 and 5π/6

2sin(x) = 1 gives sin(x) = 1/2, which is true at x = π/6 and x = π - π/6 = 5π/6 in [0, 2π).

5. What is the cotangent of 90°?
0

cot(90°) = cos(90°)/sin(90°) = 0/1 = 0.

6. Which identity is equivalent to sin²x + cos²x?
1

The Pythagorean identity states sin²x + cos²x = 1 for all x.
