Step-by-step explanation:
We have to prove the identity
![tan(\frac{\Theta }{2})=\frac{sin\Theta}{1+cos\Theta }](https://tex.z-dn.net/?f=tan%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%3D%5Cfrac%7Bsin%5CTheta%7D%7B1%2Bcos%5CTheta%20%7D)
We will take right hand side of the identity
![\frac{sin\Theta}{1+cos\Theta}=\frac{2sin(\frac{\Theta }{2})cos(\frac{\Theta }{2})}{1+[2cos^{2}(\frac{\Theta }{2})-1]}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%5CTheta%7D%7B1%2Bcos%5CTheta%7D%3D%5Cfrac%7B2sin%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29cos%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%7D%7B1%2B%5B2cos%5E%7B2%7D%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29-1%5D%7D)
![=\frac{2sin(\frac{\Theta }{2})cos(\frac{\Theta }{2})}{2cos^{2}(\frac{\Theta }{2})}=\frac{sin(\frac{\Theta }{2})}{cos(\frac{\Theta }{2})}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2sin%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29cos%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%7D%7B2cos%5E%7B2%7D%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%7D%3D%5Cfrac%7Bsin%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%7D%7Bcos%28%5Cfrac%7B%5CTheta%20%7D%7B2%7D%29%7D)
[ Tan θ will be positive since θ lies in 1st quadrant ]
Answer:
3/100 times 3 is 0.09 or 9/100
Answer:
In the given expression, 10x + 8, the numerical coefficient is 10 and the literal coefficient is x. The number 8 is not considered as a coefficient since the value is a constant.
5y - 6 = 18. Add 6 to both sides. 5y = 24. Divide by five and you end up with y = 24/5, which could also be written as 4.8.
i think maybe 2,7 Sorry if i’m wrong
