Given that cos(theta)=a/b, what is the value of theta (circle with line through it)
\n" ); document.write( "Right angles triangle
\n" ); document.write( "angles 60 30 and 90 degrees
\n" ); document.write( "----
\n" ); document.write( "theta = cos^1(a/b)
\n" ); document.write( "Or
\n" ); document.write( "theta = arccos(a/b)
\n" ); document.write( "==========
