`(tan35^(@)/cot55^(@))+(cos78^(@)/sin(1 2^(@)))-1`

Evaluate the following : (tan35^(@))/(cot55^(@))+(cot78^(@))/(tan12^(@))-1

The value of ((tan35^(@))/(cot55^(@))+(cot78^(@))/(tan12^(@))) is

(tan 35^(@))/(cot 55^(@))+(cot 78^(@))/(tan 12^(@))=?

Simplify (sin35^(@))/(cos55^(@))+(cos55^(@))/(sin35^(@))-2cos^(2)60^(@)

Evaluate the following: (i) (tan35^@)/(cot55^@)+(cot78^@)/(tan12^@)-1 (ii) (sec70^@)/(cos e c\ 20^@)+(sin59^@)/(cos31^@)

Evaluate : (sin 35^(@) cos 55^(@) + cos 35^(@) sin 55^(@))/ (cosec^(2) 10^(@) - tan^(2) 80^(@))

((sin 35^(@))/(cos 55^(@)))^(2)-((cos55^(@))/(sin 35^(@)))^(2) +2 sin 30^(@) is equal to

tan(55^(@)+x)=cot(35^(@)-x)

Evaluate : (i) (cos 55^(@))/(sin 35^(@)) + (cot 35^(@))/(tan 55^(@)) (ii) sin 42^(@) sin 48^(@) - cos 42^(@) cos 48^(@)
