`(cot 50^@)/(tan 40^@)`

Show that : (cot(90^(@)-theta)*sin(90^(@)-theta))/(sintheta)+(cot50^(@))/(tan40^(@))=2

Show that : (cot(90^(@)-theta)*sin(90^(@)-theta))/(sintheta)+(cot50^(@))/(tan40^(@))=2

The value of (cot50^@)/(tan40^@)-1/2 cos55^@/sin35^@ is:

Evaluate : (tan20^@)/(cot70^@) +(cot50^@)/(tan40^@)+(sin^2 20^@+sin^2 70^@)/(sinthetacos(90-theta)+costhetasin(90-theta) .

(3 cot 40^(@))/(tan 50^(@)) - (1)/(2)((cos 35^(@))/(sin 55^(@))) = _________

The value of (cot 40^(@))/(tan50^(@))-(1)/(2)(cos35^(@))/(sin55^(@)) is :

Evaluate : (cot40^(@))/(tan50^(@))-(1)/(2)((cos30^(@))/(sin60^(@)))

(3cot40^(@))/(tan50^(@))- (1)/(2)((cos35^(@))/(sin55^(@))) = …………

Solve the following : (2sin22^@)/(cos68^@)-(2cot75^@)/(5 tan15^@)-(8 tan 45^@ tan20^@ tan 40^@ tan 50^@ tan70^@)/5
