In the applet below, use [b]INVERSE TRIGONOMETRIC FUNCTIONS[/b] to write [b]EXACT EXPRESSIONS[/b] for the measures of the acute angles ([b][color=#38761d][i]A[/i] [/color][/b]and [i][b][color=#1e84cc]B[/color][/b][/i]) in the [color=#bf9000][b]right triangle displayed. [/b][/color] [br][br]Be sure to enter [b]EXACT VALUES[/b] (and not decimal approximations).  [br][br]For example, to input the expression [math]sin^{-1}\left(\frac{\sqrt{13}}{5}\right)[/math] , simply enter "arcsin(sqrt(13)/5)" -- without the quotation marks.  [br][br][b]KEY:  [/b][br]arcsin(.... means ARCSINE OF....[br]arccos(.... means ARCCOSINE OF... [br]arctan(... means ARCTANGENT OF...[br]sqrt(... means SQUARE ROOT OF...[br][b][br]You should be able to write the measure of each angle in 3 DIFFERENT WAYS.  [/b]To clear any entered expression at any time, simply click the [b]"Reset Answer"[/b] button.  [br][br][color=#ff00ff][b]If you enter a correct expression for any angle, the applet will indicate this to you.[/b][/color]
