according to question we have to find the
place value of cos28°÷sin62°
as we now sin (96-0)=cos
cos(96°) sin=11
put=62° in(11) equation
cos(96-62)= sin 62°
cos28°=sin 62°=3
now put value to sin62°
cos28°= cos28°=1
sin 62°. cos28°
cos28°
sin62°
simply we can solve by converting cos 28°in sin 62°
we can right
cos 28°= cos= sin 90°=tan 45 equal to 1 sin 62°
