Answer:
Terms: 4
Degree: 3
Leading coeff: 7
Step-by-step explanation:
a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by division. 7x³+5x²-3x+1 would have 4 terms: 7x³, 5x², -3x, and 1
You already have the degree which is the highest power in a polynomial
The leading coefficent is the coefficient in the term with the highest power, in this case being 7.
hope this helps!

Step-by-step explanation:
Given
![\sin(\theta) = -1](https://tex.z-dn.net/?f=%5Csin%28%5Ctheta%29%20%3D%20-1)
Required
Determine ![\tan(\theta)](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29)
We know that:
![\sin^2(\theta) + \cos^2(\theta) = 1](https://tex.z-dn.net/?f=%5Csin%5E2%28%5Ctheta%29%20%2B%20%5Ccos%5E2%28%5Ctheta%29%20%3D%201)
This gives:
![(-1)^2 + \cos^2(\theta) = 1](https://tex.z-dn.net/?f=%28-1%29%5E2%20%2B%20%5Ccos%5E2%28%5Ctheta%29%20%3D%201)
![1 + \cos^2(\theta) = 1](https://tex.z-dn.net/?f=1%20%2B%20%5Ccos%5E2%28%5Ctheta%29%20%3D%201)
Collect like terms
![\cos^2(\theta) = 1 -1](https://tex.z-dn.net/?f=%5Ccos%5E2%28%5Ctheta%29%20%3D%201%20-1)
![\cos^2(\theta) = 0](https://tex.z-dn.net/?f=%5Ccos%5E2%28%5Ctheta%29%20%3D%200)
Take square roots
![\cos(\theta) = \sqrt 0](https://tex.z-dn.net/?f=%5Ccos%28%5Ctheta%29%20%3D%20%5Csqrt%200)
![\cos(\theta) = 0](https://tex.z-dn.net/?f=%5Ccos%28%5Ctheta%29%20%3D%200)
By tan identity
![\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29%20%3D%20%5Cfrac%7B%5Csin%28%5Ctheta%29%7D%7B%5Ccos%28%5Ctheta%29%7D)
![\tan(\theta) = \frac{-1}{0}](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29%20%3D%20%5Cfrac%7B-1%7D%7B0%7D)
