Sorry bro I’m in algebra 1 not calculus but good luck bro ✊
Considering the unit circle, it is found that the sine is negative on the third and on the fourth quadrant.
<h3>What is the unit circle?</h3>
For an angle
the unit circle is a circle with radius 1 containing the following set of points:
.
Hence, from the above explanation, the sine is negative when y is negativem, which is on the third and on the fourth quadrant.

Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is
![y=x^3-4x^2+9x-36](https://tex.z-dn.net/?f=y%3Dx%5E3-4x%5E2%2B9x-36)
To find the roots we have to equate the equation to zero
ie, ![x^3-4x^2+9x-36=0](https://tex.z-dn.net/?f=x%5E3-4x%5E2%2B9x-36%3D0)
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)

Step-by-step explanation:</h2><h3>now what do we divide by 3 to get 5 = 15</h3><h3>now lets swap the n with the 15 to get</h3><h3>4^(
![\frac{15}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B3%7D)
