Answer:
1. 7/3 = 2.3333...
2.
3. 3/4 = 0.75
4. = 4.898979486
5. = 0.4082482905
Step-by-step explanation:
Use scientific calculator or by trigonometric ratios
- In using a scientific calculator, only sine (sin), cosine (cos) and tangent (tan) functions are there so you will use the reciprocal identities. sec(∅) = 1 / sin(∅)
csc(∅) = 1 / cos(∅)
cot(∅) = 1 / tan(∅)
Then, you can plug in to your scientific calculator. Be sure to use parentheses and you input correct exponent, operations or angles. And most important is your calculator must be in degree mode.
