theta)^(2)quad " 2.Evaluate tan "15^(@)

If tan theta+(1)/(tan theta)=2, find the value of tan^(2)theta+(1)/(tan^(2)theta)

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 .

Prove that, cot ( theta + 15^(@))- tan(theta - 15^(@))=(4 cos 2 theta)/(1+2 sin 2 theta)

If tan theta+cot theta=2, find the value of tan^(2)theta+cot^(2)theta

If (sin theta+cos theta)/(sin theta-cos theta)=(5)/(3) evaluate (7tan theta+2)/(2tan theta+7)

If theta is an acute angle and tan theta + cot theta=2 find the value of tan^(7)theta+cot^(7)theta

If theta is an acute angle and tan theta+cot theta=2 find the value of tan^(7)theta+cot^(7)theta

if 15tan^(2)theta+4sec^(2)theta=23 then tan^(2)theta=

If tan theta + cot theta =2 , find the value of sqrt(tan^(2) theta + cot^(2) theta) .

If 3 tan (theta - 15^@) = tan (theta + 15^@) , then the general value of theta is
