Answer:
Hence value for x is 0 degree
Step-by-step explanation:
Given:
x limits are (0 to 360) degrees and
Cos(x+45)+cos(x-45)=Sqrt(2)
To Find:
value for X
Solution:
Given equation cos(x+45)+ cos(x-45)
Is similar to cos(A+B) +cos(A-B)=2cosA*cosB
Now comparing with general formula we get ,
A=x and B=45
S
Hence given equation becomes as ,
x= 0
Hence value for x is 0 degree

first simplify each
14/18=2/2 times 7/9=1 times 7/9=7/9
16/20=2/2 times 2/2 times 4/5=1 times 4/5=4/5
7/9 and 4/5
make bottom number same
7/9 times 5/5=35/45
4/5 times 9/9=36/45
36/45>35/45

Answer:
Cos(π/2 - θ) = A
Step-by-step explanation:
We know that:
Sin(θ) = A
And we want to find the value of Cos(π/2 - θ)
Here we can use the cosine relationship:
Cos(a - b) = Cos(a)*Cos(b) + Sin(A)*Sin(B)
Then:
Cos(π/2 - θ) = Cos(π/2)*Cos(θ ) + Sin(π/2)*Sin(θ)
We know that:
Cos(π/2) = 0
Sin(π/2) = 1
Then:
Cos(π/2 - θ) = Cos(π/2)*Cos(θ ) + Sin(π/2)*Sin(θ) = 0*Cos(θ ) + 1*Sin(θ)
= 1*Sin(θ) = A
Cos(π/2 - θ) = A
Answer:
2 and 3
Step-by-step explanation:
subtract (-5) - (-12) and get 7 plus if you see a - that is finding the difference. therefore your answers are 2 and 3. Hope this helps! ^w^
