1.	Evaluate the following : (i)`(sin58^(@))/(cos32^(@))` (ii) `(sec42^(@))/("cosec"48^(@))` (iii)`(tan37^(@))/(cot53^(@))`
Answer» (i) `(sin58^(@))/(cos32^(@)) =(sin(90^(@)=32))/(cos32^(@))=(cos32^(@))/(cos32^(@))=1` (ii) `(sec42^(@))/("cosec"48^(@))=(sec(90^(@)-48))/("cosec"48^(@))=("cosec"48^(@))/("cosec"48^(@))=1` (iii) `(tan37^(@))/(cot53^(@))=(tan(90^(@)-53^(@)))/(cot53^(@))=(cot53^(@))/(cot53^(@))=1`
