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:
True
Step-by-step explanation:
Given are some sets A, B, C, D and Universal set U.
We have
When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only
Hence here A' = =A
This is because whenever we take any element x in A this belongs to A'
Hence
Similarly any element y in A' also belongs to A
So A⊂A'
Together we have
Option d true
