 Description
 e2.301 Express  in terms of i)   , and ii)  , and iii)  ; the latter part is more difficult than the preceding two parts.  Each square root that appears is assumed to include both positive and negative roots; for arbitrary angle , the sign of the root is given by the quadrant of the angle.  Test your results with a numerical value of . In an analogous manner, each circular trigonometric function is expressible in terms of any other circular trigonometric function, but possible ambiguity of signs of square roots exists.    eq := [sin(theta)^2 + cos(theta)^2 - 1,
