निम्नलिखित के मान ज्ञात कीजिए:
(i) `( sin 58^(@))/(cos 32^(@))`
(ii) `(sec 42^(@))/(cosec 48^(@))`
(iii) `(tan 37^(@))/(cot 53^(@))`

Explanation

(i) `(sin 58^(@))/(cos 32^(@)) = ( sin (90^(@)-32^(@)))/( cos 32^(@)) = (cos 32^(@))/(cos 32^(@)) =1`
(ii) `(sec 42^(@))/(cosec 48^(@)) = ( sec990^(@) - 48^(@))/(cosec 48^(@)) = (cosec 48^(@))/(cosec 48^(@)) =1`
(iii) `( tan 37^(@))/(cot 53^(@)) = (tan (90^(@) - 53^(@)))/(cot 53^(@)) = (cot 53^(@))/(cot 53^(@)) = 1`
