निम्नलिखित के मान ज्ञात कीजिए:(i) ( sin 58^(@))/(cos 32^(@)) (ii) (sec 42^(@))/(cosec 48^(@)) (i...

Evaluate the following : (i) (sin58^(@))/(cos32^(@)) (ii) (sec42^(@))/("cosec"48^(@)) (iii) (tan37^(@))/(cot53^(@))

((sin48^(@))/(cos42^(@)))+((cos48^(@))/(sin42^(@)))=2

(sin48^(@))/(cos42^(@))+(cos48^(@))/(sin42^(@))=2

Evaluate : (i) tan42^(@)-cot48^(@) (ii) sec36^(@)-"cosec"54^(@)

sin42^(@)sec48^(@)+cos42^(@)cos ec48^(@)=2

sin48^(@)sec42^(@)+cos48^(@)csc42^(@)=
