Answer:
The general solution of
is
x = 2nπ±
The general solution values

Step-by-step explanation:
Explanation:-
Given equation is


Dividing '2' on both sides, we get


<em>General solution of cos θ = cos ∝ is θ = 2nπ±∝</em>
<em>Now The general solution of </em>
<em> is </em>
<em> x = 2nπ±</em>
<em></em>
put n=0

Put n=1


put n=2


And so on
But given 0 < x< 2π
The general solution values

Answer:
41/60
Step-by-step explanation:
Convert the fractions into like denominators: 7/30 = 140/600, 9/20 = 270/600
Add: 140/600+270/600 = 410/600
Divide into a smaller fraction: 41/60
