Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
The change of amplitude of a sound wave's amplitude is linked to the change in pressure that occurs due to the wave measured at a given location.
Frequency tells the number of waves that pass a fixed location in a specific time frame.
<h3>How does sound waves relate to trigonometric functions?</h3>
Sound engineers uses the basic laws of trigonometry via sine and cosine graphs.
Note that all sounds can be broken down into a lot of sine waves, as sine waves comes together to form sounds.
Therefore, Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.

We want to see if Clare and Diego estimations of the slope are correct or not. We will see that Clare overestimated a little bit the slope and Diego got it correct.
<h3>How to compare estimations</h3>
First, we do know that the exact slope of the triangle is 2/3.
First, Clare says that the slope is given by a ratio of 2.8 : 4.1, now we can take the quotient of these two numbers and see if it is something like 2/3
2.8/4.1 = 0.683
While the actual slope is:
2/3 = 0.666....
So we can see that her measure gives a slope that is a bit larger than the actual one.
For the case of Diego, he says that the slope is 0.67
Note that if we take the actual slope and we round it at the second digit after the decimal point, we get:
0.666... ≈ 0.67
Which is the same thing that Diego got, so his measure is actually correct.
