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

Try sketching the following graphs

the graph of y= csc(2x) should repeat it self 😣! I'm sorry for bothering you. You can just ignore me now.

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 units

 

[mustafa5255]

it is repeating it just lags by pi/2 units

exactly!!! But whyy?

 

[Hamnah Zahoor]

ok now you are confusing me too
you are asking why is it lagging?

 

[mustafa5255]

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?

 

[Hamnah Zahoor]

exactly!!! But whyy?

open this website and read each and every detail there given of the graph of how he generalized the equation and how the phase shift was calculated.
if you still don't understand it than ask here again.

 

[Hamnah Zahoor]

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

 

[mustafa5255]

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.

AOA. stuck on this question can anyone plz help.

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°.

'1' quadrant is (1,1) ; '-1' quadrant is (1,-1) ; what are quadrants (-1,1) and (-1,-1)?
