Use reciprocal identities to give the value of each expression\r
\n" ); document.write( "\n" ); document.write( " a. If cos θ = 1/5, what is sec θ?
\n" ); document.write( "sec = 1/cos = 5
\n" ); document.write( "------------------
\n" ); document.write( " b. If csc θ = 3/4, what is sin θ?
\n" ); document.write( "sin = 1/csc\r
\n" ); document.write( "\n" ); document.write( "sin > 1 --> no real number solution
\n" ); document.write( "------------------
\n" ); document.write( " c. If tan θ = 5/12 and sin θ = 5/13, what is sec θ?
\n" ); document.write( "sec^2 = tan^2 + 1
\n" ); document.write( "sec^2 = 25/144 + 1 = 169/144
\n" ); document.write( "sec = 13/12
\n" ); document.write( "-------
\n" ); document.write( "Or
\n" ); document.write( "tan = sin/cos
\n" ); document.write( "cos = sin/tan = (5/13)/(5/12) = 12/13
\n" ); document.write( "sec = 13/12 \n" ); document.write( "
\n" );
