What is sin theta when cos theta is 0

Divide by costheta

You get Sin(theta)/Cos(theta) + Cos(theta)/cos(theta) =0

[Sinx/cosx = tanx (a law of trigs)]

so the same as tan(theta) + 1=0

So tan(theta)=-1

Inverse tan/arctan (-1) =3/4 pi and (2pi - 3/4pi) = 7/4pi

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
