I have crossed the values from the given limits for a clearer image

the graph of y= csc(2x) should repeat it self 😣! I'm sorry for bothering you. You can just ignore me now.
it is repeating it just lags by pi/2 unitsthe graph of y= csc(2x) should repeat it self 😣! I'm sorry for bothering you. You can just ignore me now.
exactly!!! But whyy?it is repeating it just lags by pi/2 units
I'm so sorry but yes thats what im asking. The graph of y=csc2x should be the same as y=csc(2x-pi) but it only shift pi/2 units to the right, why?ok now you are confusing me too
you are asking why is it lagging?
exactly!!! But whyy?
I didnt know thats how you get the phase shift. I first sketched the graph of y=csc(2x) and then shifted it pi units to the right (y=csc(2x-pi)) is this wrong? I've been doing this for a long time and always got the right answers.do the same for the other equation csc(2x)
I get it now. Thank you soo muchh!! I couldn't afford a school or academy so studying all by myself and this helped alot. Thanks again.

'1' quadrant is (1,1) ; '-1' quadrant is (1,-1) ; what are quadrants (-1,1) and (-1,-1)?R=√10
a= 71.56
(√10) cos (2x - 71.57) = 2
The range in which we've to find the angle is 0<Θ<90 but we'll be needing to modify it.
0<Θ<90
multiply it by '2'.
0<2Θ<180
Subtract 71.56 from both the limits.
-71.56<2Θ<108.44
So according to this range, we'll be needing to find the angle in three quadrants; -1, 1 and 2.
(√10) cos (2Θ - 71.57) = 2
cos (2Θ - 71.57) = 0.6324
2Θ - 71.57 = 50.78
As the angle we've found is positive which in turn means that 'cos' is positive, we'll find the angle in the quadrant in which 'cos' is positive. 'Cos' is positive in the '-1' quadrant and the '1' quadrant; thus, it is quiet easy to find the value of Θ now.
'-1' quadrant:
2Θ - 71.57 = -50.78
2Θ = 20.79°
Θ = 10.4°
'1' quadrant:
2Θ - 71.57 = 50.78
2Θ = 122.35
Θ = 61.1°
Therefore, the 2 values of Θ are 10.4° and 61.1°.
