Daniel is standing outside of his apartment building because his cable company cut off his service. He is watching his second favorite show through his neighbor's window. The cosine of the angle of elevation (0) from Daniel to the apartment is 12/13. He suddenly notices that his neighbor on the next floor is watching his favorite show and adjusts his view so that his angle of elevation is double what it was before. (express your answers in fraction form, e.g. 3/4) Determine the following trigonometric functions: cos e = sin e = Find the cosine of the new angle of elevation.
