$\"%281-Cos%5E2theta%29%2F%28Cos%5E2theta%29\"$
\n" ); document.write( "
\n" ); document.write( "There is an identity that goes $\"Sin%5E2theta%2BCos%5E2theta=1\"$ which can
\n" ); document.write( "be written as $\"Sin%5E2theta=1-Cos%5E2theta\"$ \r
\n" ); document.write( "\n" ); document.write( "So replace the numerator by $\"Sin%5E2theta\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28Sin%5E2theta%29%2F%28Cos%5E2theta%29\"$ \r
\n" ); document.write( "\n" ); document.write( "which can be written\r
\n" ); document.write( "\n" ); document.write( " $\"%28Sin%28theta%29%2FCos%28theta%29%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( "There is an identity that goes $\"%28Sin%28theta%29%29%2F%28Cos%28theta%29%29=Tan%28theta%29\"$ \r
\n" ); document.write( "\n" ); document.write( "So the final answer is\r
\n" ); document.write( "\n" ); document.write( " $\"%28Tan%28theta%29%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( "or\r
\n" ); document.write( "\n" ); document.write( " $\"Tan%5E2theta\"$ , choice c)\r
