Note: tan z = (sin z/ cos z) ;
tan z = (4/5) / (3/5) ;
= [tex] \frac{4}{5} [/tex] * [tex] \frac{5}{3} [/tex] ;
Note: Both of the "5 ' s" cancel out to "1" ; since: "{5 ÷ 5 = 1 }" ;
And we rewrite as:
→ " [tex] \frac{4}{1} [/tex] * [tex] \frac{1}{3} [/tex] " ;
= [tex] \frac{(4*1)}{(1*3)} [/tex] ;
= " [tex] \frac{4}{3} [/tex] " .
