Certainly! To determine the three basic trigonometric ratios, let's list them step by step.
The three fundamental trigonometric ratios in trigonometry are:
1. Sine (sin): This ratio represents the length of the opposite side to the hypotenuse in a right triangle.
2. Cosine (cos): This ratio represents the length of the adjacent side to the hypotenuse in a right triangle.
3. Tangent (tan): This ratio represents the length of the opposite side to the adjacent side in a right triangle.
These three ratios are often referred to as the primary trigonometric functions because they form the foundation upon which other trigonometric concepts are built.
Given the choices:
A. sine
B. secant
C. cosine
D. tangent
The correct answers are:
- A. sine
- C. cosine
- D. tangent
So, the selected three basic trig ratios are: sine, cosine, and tangent.
Submission:
A. sine
C. cosine
D. tangent
