Answer:
Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.
Step-by-step explanation:
Recall the Trigonometric Ratio below:
For csc, sec and cot - they are reciprocal of sin,cos and tan.
What we know now is our hypotenuse, adjacent and opposite length.
- hypotenuse = 15
- opposite = 12
- adjacent = 9
Therefore,
As for the reciprocal of three trigonometric ratio. We just swap the numerator and denominator.
Answer
- sin = 12/15 —> 4/5
- cos = 9/15 —> 3/5
- tan = 12/9 —> 4/3
- csc = 15/12 —> 5/4
- sec = 15/9 —> 5/3
- cot = 9/12 —> 3/4
The first is non-simplifed form while the second that has the arrow pointing is the simplest form.
