`Cot(1358^@)+ tan (3608^@)`

tan 585^(@) * cot 405^(@) + tan 675^(@) * cot 765^(@)=

Prove that tan 315^(@) cot ( -405^(@) ) + cot 495^(@) tan (-585^(@)) = 2

Prove that: tan(-225^(@))cot(-405^(@))-tan(-765^(@))cot(675^(@))=0

The value of (cot 54^(@))/(tan 36^(@)) + (tan 20^(@))/(cot 70^(@)) is

tan A+cot(180^(@)+A)+cot(90^(@)+A)+cot(360^(@)-A)=

The value of cot54^@/(tan36^@) +tan20^@/(cot70^@)=

The value of (cot54^(@))/(tan36^(@))+(tan20^(@))/(cot70^(@)) is

Find the value of (cot 25^(@)+cot 55^(@))/(tan 25^(@)+tan55^(@))+(cot 55^(@)+cot 100^(@))/(tan 55^(@)+tan 100^(@))+(cot 100^(@)+cot 25^(@))/(tan 100^(@)+tan 25^(@))
