begin mathsize 16px style fraction numerator sin space straight theta minus cos space straight theta over denominator sin space straight theta plus cos space straight theta end fraction equals 3 over 5
rightwards double arrow fraction numerator begin display style 7 tan space straight theta plus 2 end style over denominator begin display style 7 plus 2 tan space straight theta end style end fraction
equals fraction numerator 7 begin display style fraction numerator sin space straight theta over denominator cos space straight theta end fraction end style plus 2 over denominator 7 plus 2 begin display style fraction numerator sin space straight theta over denominator cos space straight theta end fraction end style end fraction
equals fraction numerator begin display style fraction numerator 7 sin space straight theta plus 2 cos space straight theta over denominator cos begin display style space end style begin display style straight theta end style end fraction end style over denominator begin display style fraction numerator 7 cos space straight theta plus 2 sin space straight theta over denominator cos begin display style space end style begin display style straight theta end style end fraction end style end fraction
equals fraction numerator 7 sin space straight theta plus 2 cos space straight theta over denominator 7 cos space straight theta plus 2 sin space straight theta end fraction
equals fraction numerator 7 sin space straight theta plus 2 cos space straight theta plus 7 cos space straight theta plus 2 sin space straight theta over denominator 7 sin space straight theta plus 2 cos space straight theta minus 7 cos space straight theta minus 2 sin space straight theta end fraction
equals fraction numerator begin display style 9 sin space straight theta plus 9 cos space straight theta end style over denominator begin display style 5 sin space straight theta minus 5 cos space straight theta end style end fraction
equals 9 over 5 cross times fraction numerator begin display style sin space straight theta plus cos space straight theta end style over denominator begin display style sin space straight theta minus cos space straight theta end style end fraction
equals 9 over 5 cross times 5 over 3
equals 3
end style
