(cot50^(@))/(tan40^(@))

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

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

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

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

Evaluate the following: (i) (cot40^@)/(tan50^@)-1/2((cos35^@)/(sin55^@)) (ii) ((sin27^@)/(cos63^@))^2-((cos63^@)/(sin27^@))^2

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

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

Evaluate the following: (i) (cot40o)/(tan50o)-1/2((cos35o)/(sin55o)) (ii) ((sin27o)/(cos63o))^2-((cos63o)/(sin27o))^2

Without using trigonometric tables , evaluate the following : (cot(90^(@)-theta)*sin(90^(@)-theta))/(sintheta)+(cot40^(@))/(tan50^(@))-(cos^(2)20+cos^(2)70^(@))
