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

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

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

The value of tan 57^(@) - tan 12^(@) - tan 57^(@) tan 12^(@) is

Evaluate: (cos 55^(@))/(sin 35^(@))+(cot 35^(@))/(tan 55^(@))

Value of tan 35^@ - cot 55^@

The value of (tan10^(@)+tan35^(@))+tan10^(@)tan35^(@) is

Value of tan25^(@)tan35^(@)tan45^(@)tan55^(@)tan65^(@) is

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

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