How do you find sin, cos, and tan? What does SOH CAH TOA stand for? What are the reciprocal of sin, cos, and tan?
Practice Skills
How do you find the six basic trigonometric functions. Which ones are important?
You are given a right triangle. Theta is located ACROSS from the right angle. The hypotenuse is 25, the flat side of the triangle is 8, and the opposite of theta is 13. What is csc, sec, and cot?
Explain what SOH CAH TOA is and how do you use it. What does the acronym stand for?

- Sine (sin)
- Cosine (cos)
- Tangent (tan)
- Secant (sec)
- Cosecant (csc)
- Cotangent (cot)
- a is the length of the side adjacent to the angle (x) in question.
- o is the length of the side opposite the angle.
- h is the length of the hypotenuse.
Critical Questions
Why do you think that csc, sec, and cot are easily less deprived? Why isn't it important? How and why is sin, cos, and tan important? Where and when in the world of trigonometry is it used? Give at least three examples. Do we need trigonometry? Why or why not?
Define what opposite, adjacent, and hypotenuse mean. When do we use them?
