Step-by-step explanation:
Given that a curve in polar coordinates is given by:
r=9+3cosθ
a) At point P, we have
![θ=\frac{21\pi}{18}](https://tex.z-dn.net/?f=%CE%B8%3D%5Cfrac%7B21%5Cpi%7D%7B18%7D)
Substitute to get
![r=9+cos \frac{21\pi}{18}\\=9.3932](https://tex.z-dn.net/?f=r%3D9%2Bcos%20%5Cfrac%7B21%5Cpi%7D%7B18%7D%5C%5C%3D9.3932)
b) Cartesian coordinate is
![x= rcos \theta=3.6934\\y =r sin \tjeta =8.6365](https://tex.z-dn.net/?f=x%3D%20rcos%20%5Ctheta%3D3.6934%5C%5Cy%20%3Dr%20sin%20%5Ctjeta%20%3D8.6365)
c) At the origin r =0
when r =0
we have
![9+3cos\theta=0\\cos\theta =-3](https://tex.z-dn.net/?f=9%2B3cos%5Ctheta%3D0%5C%5Ccos%5Ctheta%20%3D-3)
Since cos cannot take values as -3 it doe snot pass through origin.
Answer:
2 complex conjugates
Step-by-step explanation:
The discriminate is the part of the quadratic formula that is under the radical sign. If the discriminate is negative, that means that the solutions, both of them, are complex conjugates, aka imaginary solutions.
