In each of the following equations determine which variable
     In each of the following equations, determine which variable represents the angle and which variable represents the value of the trigonometric function.  (a) In the equation q = sin d, represents the angle and represents the value of the trigonometric function.  (b) In the equation p = tan^1 c, represents the angle and  represents the value of the trigonometric function.  (c) In the equation arccos n = upsilon, represents the angle and  represents the value of the trigonometric function. 
  
  Solution
a) d represents the angle and q represents the value
b)p represents the angle and c represents the value
c) v represents the angle and n represents the value
