If `theta_1 and theta_2` are the angles made by the lines `(x^2 +y^2)(cos^2theta sin^2 theta+sin^2theta)=(x tan alpha-y sin theta)^2` with positive axis of x in the anti-clock wise direction, if `theta=pi/6, tan theta_1 + tan theta_2` equals

If theta_(1) and theta_(2) are the angles made by the lines (x^(2)+y^(2))(cos^(2)theta sin^(2)theta+sin^(2)theta)=(x tan alpha-y sin theta)^(2) with positive axis of x in the anti-clock wise direction, if theta=(pi)/(6),tan theta_(1)+tan theta_(2) equals

tan^2theta-sin^2theta=tan^2theta.sin^2theta

(1+sin2 theta-cos2 theta)/(1+sin2 theta+cos2 theta)=tan theta

Prove that: (sin2 theta)/(1+cos2 theta)=tan theta

Prove that: (sin2 theta)/(1+cos2 theta)=tan theta

(sin theta+sin2 theta)/(1+cos theta+cos2 theta)=tan theta

(sin theta+sin2 theta)/(1+cos theta+cos2 theta)=tan theta

Prove that (1+sin2 theta)/(1-sin2 theta)=((1+tan theta)/(1-tan theta))^(2)

Prove that (1+sin2 theta)/(1-sin2 theta)=((1+tan theta)/(1-tan theta))^(2)

if tan theta=(a)/(b), then cos2 theta+a sin2 theta equal to
