Trigonometric Equations
Bayani Gaba-gaba
A trigonometric identity is true for every angle, but a trigonometric equation is true only for particular values. Finding all of those values inside a given interval is one of the most satisfying skills in the 4PM1 course, and it appears on almost every exam paper.
You will learn to solve equations involving sin, cos, and tan by combining reference angles with the CAST diagram, tackle quadratic forms by substitution, handle multiple-angle equations such as sin 3x = k, and apply identities to reduce more complex equations to solvable standard forms. Every technique is grounded in a systematic method that examiners reward with full marks.

- How many solutions does sin x = 0.5 have in the interval 0 to 360 degrees? A) 1 B) 2 C) 3 D) 4 Answer: B
- In the CAST diagram, which trigonometric ratio is positive in the third quadrant? A) Sin B) Cos C) Tan D) All Answer: C
- Solve tan theta = 1 for 0 <= theta < 360 degrees. The solutions are: A) 45 degrees only B) 45 and 135 degrees C) 45 and 225 degrees D) 45, 135, 225, and 315 degrees Answer: C
- To solve sin 2theta = 0.5 for 0 <= theta <= 360 degrees, you should first: A) Divide both sides by 2 B) Let u = 2theta and solve for u in 0 <= u <= 720 C) Use the identity sin 2theta = 2 sin theta cos theta D) Square both sides Answer: B
- Which identity would you use first to solve 3 sin theta = 4 cos theta? A) sin squared + cos squared = 1 B) Divide by cos theta to get tan theta C) sin 2theta = 2 sin theta cos theta D) cos 2theta = 1 - 2 sin squared theta Answer: B
