दिखाइए कि `sin 28^(@) cos 62^(@)+cos28^(@) sin 62^(@)=1`

(cos 28^(@))/(sin 62^@)=?

(cos 28^(@))/(sin 62^(@))=?

(cos 62^@)/(sin 28^@) =?

cos 56 ^(@) + cos 58^(@) - cos 66^(@) - 4 cos 28^(@) cos 29^(@) sin 33 ^(@) =

Find : cos 62^(@) 27'

Consider the following : 1. (cos 75^(@))/(sin 15^(@)) + (sin 12^(@))/(cos 78^(@)) - (cos 18^(@))/(sin 72^(@)) =1 2. (cos 35^(@))/(sin 55^(@)) - (sin 11^(@))/(9cos 79^(@)) + cos 28^(@) "cosec" 62^(@) =1 3. (sin 80^(@))/(cos 10^(@)) - sin 59^(@).sec 31^(@) =0 Which of the above are correct ?

Show that 1+cos 56^(@)+ cos 58^(@)-cos66^(@)=4 cos 28^(@) cos 29^(@) sin 33^(@)

cos62^@/(sin28^@)=?

(1+ cos 56^(@) + cos 58^(@) - cos 66^(@))/( cos 28^(@) cos 29^@ sin 33^(@) )=

( cos 17^(@) + sin 17^(@))/( cos 17^(@) - sin 17^(@)) = tan 62^(@)
