3tan(theta-15^(@))=tan(theta+15^(@))

If 3 tan (theta-15^(@))=tan(theta+15^(@)), 0lt thetalt pi,then theta=

If 3 tan (theta - 15^(@))=tan (theta + 15^(@)), 0 lt theta lt pi then theta =

If tantheta-cottheta=0andtheta is positive acute angle , then the value of (tan(theta+15^(@)))/(tan(theta-15^(@))) is

cot(theta+15^(@))-tan(theta-15^(@))=(4cos2 theta)/(1+2sin2 theta) prove that

If 3tan(theta-15^0)=tan(theta+15^0), then theta is equal to n in Z)

If 3tan(theta-15^0)=tan(theta+15^0), then theta is equal to n in Z) n pi+pi/4 (b) npi+pi/8 npi+pi/3 (d) none of these

If 3tan(theta-15^0)=tan(theta+15^0), then theta is equal to n in Z) n pi+pi/4 (b) npi+pi/8 npi+pi/3 (d) none of these

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

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