Hi there,
\n" ); document.write( "If sin theta = 3/5
\n" ); document.write( "Construct a right angled triangle
\n" ); document.write( "Give the hypotenuse the value of 5
\n" ); document.write( "Give the opposite side the value of 3
\n" ); document.write( "Then the adjacent side will have a value of 4
\n" ); document.write( "This is a 3,4,5 right angled triangle
\n" ); document.write( "then,
\n" ); document.write( "cos theta = 4/5
\n" ); document.write( "tan theta = 3/4
\n" ); document.write( "cot theta = 4/3
\n" ); document.write( "(cotθ-tanθ)cosθ
\n" ); document.write( "(4/3 - 3/4)4/5
\n" ); document.write( "((16 - 9)/12)4/5
\n" ); document.write( "(7/12)4/5
\n" ); document.write( "=28/60
\n" ); document.write( "= 0.4667 (4 decimal places)
\n" ); document.write( "sin^-1 0.4667 = 152.2 degrees
\n" ); document.write( "cos^-1 0.4667 = -117.8 degrees
\n" ); document.write( "tan^-1 0.4667 = -155 degrees
\n" ); document.write( "Hope this helps:-) \n" ); document.write( "
\n" );
