FAQs on Trigonometric Ratios Video Lecture - Mathematics for SAT

1. What are the three main trigonometric ratios?
Ans. The three main trigonometric ratios are sine, cosine, and tangent, often abbreviated as sin, cos, and tan, respectively.
2. How are trigonometric ratios used to solve for unknown angles or sides in a right triangle?
Ans. Trigonometric ratios can be used to solve for unknown angles or sides in a right triangle by setting up proportions and using the given ratios to find the missing values.
3. Can trigonometric ratios be used in non-right triangles?
Ans. Yes, trigonometric ratios can be used in non-right triangles by applying the Law of Sines or the Law of Cosines to determine the relationships between the angles and sides of the triangle.
4. How do you determine which trigonometric ratio to use in a given problem?
Ans. The trigonometric ratio to use in a given problem depends on the information provided and the unknown quantity being solved for. For example, if the opposite and adjacent sides are given, you would use the tangent ratio.
5. How can trigonometric ratios be applied in real-life situations?
Ans. Trigonometric ratios can be applied in real-life situations such as measuring heights of buildings or mountains, calculating distances using angles, and determining the speed of moving objects based on angles of elevation or depression.
