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
