Find the exact values of the sine, cosine, and tangent of the angle.
\n" ); document.write( "195° = 240° − 45°
\n" ); document.write( "sin(195°)
\n" ); document.write( "---
\n" ); document.write( "ain(A - B) = sin(A)cos(B) - sin(B)cos(A)\r
\n" ); document.write( "\n" ); document.write( "105° = 75° + 30° *** what about it?
\n" ); document.write( "------------
\n" ); document.write( "sin(195°)
\n" ); document.write( "195 = 150 + 45
\n" ); document.write( "ain(A + B) = sin(A)cos(B) + sin(B)cos(A)
\n" ); document.write( "
\n" ); document.write( "
\n" );
