$\"tan%28theta%29=+-7%2F24\"$
\n" ); document.write( "Second quadrant, cosine is negative, sine is positive
\n" ); document.write( " $\"sin%28theta%29=7%2FR\"$
\n" ); document.write( " $\"cos%28theta%29=-24%2FR\"$
\n" ); document.write( " $\"%287%2FR%29%5E2%2B%28-24%2FR%29%5E2=1\"$
\n" ); document.write( " $\"49%2B576=R%5E2\"$
\n" ); document.write( " $\"R%5E2=625\"$
\n" ); document.write( " $\"R=25\"$
\n" ); document.write( "So then,
