Solve using periodic properties: Sin-1(sin(5π/8)) cos (16π/3) Assuming you don't have a calculator to check your work, I don't understand how to find the corresponding angle on the periodic circle. I really need a detailed explanation. I understand the math so I don't need someone showing me how to subtract 5π-2π =3π, but more so how you would know how to subtract 5-2 as opposed to 5π-4π to get π/8? I've seen people solve many questions like these different ways,...
Z b sin xdx = cos a − cos b

You are working on a research project in which you must control the direction of travel of electrons using deflection plates. You have devised the apparatus shown in the figure below. The plates are of length ℓ = 0.250 m and are separated by a distance d = 1.65 cm. Electrons are fired at vi = 4.90 ✕ 106 m/s into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge...
