Stuck on this and don’t have a clue where I am going wrong.
It's hard to see your work from here.
But it looks like you played the instead of the .Multiply the left side byIt is given that: .
A) Find the value of
. .
Let be an angle such that: .
Then we have: .
. . . . . . . . . . . . . . .
Therefore: .
Show that: .
Since , then: .
Hence, find the maximum value of
and find a positive value of at which the maximum value occurs.
The maximum of: . occurs when
. . Then the maximum value is
If , then: .
Therefore: .
