[" Evaluar: "],[" tan "35^(@)],[" cot "55^(@)quad +(cot78^(@))/(tan12^(@))-1]

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

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

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

((tan35 ^ (@)) / (cot55 ^ (@))) + ((cos78 ^ (@)) / (sin (12 ^ (@)))) - 1

Value of tan 35^@ - cot 55^@

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

Evaluate : tan (55^(@)-A)-cot (35^(@)+A)

Evaluate : tan (55^(@)-A)-cot (35^(@)+A)

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

If A=tan6^(@) tan42^(@), B=cot66^(@) cot78^(@) then
