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

ok now you are confusing me too

you are asking why is it lagging?

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?

do the same for the other equation csc(2x)

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)

'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°.
