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.

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)?

A passerby observed Imam Ali (A.S) consuming such dried bread pieces that even a beggar would hesitate to steal them. Has Allah forbade you from consuming finer food? he questioned. Imam ALI(A.S): "No, but I want to consume food that at least some people in (my) region can afford once a day. I'll make improvements after I raise their standard of living.

Salaam, can someone help with this questions. How do we represent the equation of motion without friction but also in regard of the acceleration gained before

The acceleration value will change as the total force changes!
Hence, Fnet = ma is what you must use to find the new a.

However, this is just by reading what you provided in the images.
It would be better if you could share the exact question if available so that I can help you in much more clear way.
