`cos 37^(@)cosec 53^(@)`

(sec37^(@))/(csc53^(@))=

If cos37^(@)=(a)/(b) then , what is the valie of cosec 37^(@)-cos53^(@) ?

Evaluate the ((3 cos 43^(@))/(sin 47^(@)))^(2) - (cos 37^(@) "cosec" 53^(@))/(tan 5^(@) tan 25^(@) tan 45^(@) tan 65^(@) tan 85^(@))

Solve the following/ निम्नलिखित को हल कीजिए : (sin 40^@)/(cos 50^@)+ (cosec 50^@)/(sec 40^@)-4 cos50^@ cosec40^@

Evaluate : ( 3 cos 53^(@) cosec 37^(@))/(( cos^(2) 29^(@) + cos^(2) 61^(2))) - 3 tan ^(2) 45^(@)

Without using the trigonometric tables, evaluate the following : (11)/(7) (sin 70^(@))/(cos 20^(@)) - (4)/(7) (cos 53^(@) "cosec" 37^(@))/(tan 15^(@) tan 35^(@) tan 55^(@) tan 75^(@))
