" 2.Evaluate tan "15^(@)

Evaluate tan15^@

Evaluate : tan 15^@ tan25^@tan60^@tan65^@tan75^@ .

S.T tan alpha =(sin 2 alpha )/(1+cos 2 alpha ) . Hence find the value of tan 15^(@) and tan 22 1//2^(@)

Using the identity tan A =(sin 2A)/(1+cos2A) find the value of tan 15^(@) and tan 75^(@) and hence solve that the equation sec^(2) theta= 4 tan theta .

Find the value of tan15^(@)

Find the value of tan15^(@) .

Find the value of : tan(15^(@))

Find the value of : tan 15^@

The value of (1- tan 15^(@))/(1 + tan 15^(@))
