Solve: cottheta +cos e ctheta=sqrt(3)

Solve: cottheta +cos e ctheta=sqrt(3)

If t a nthetaa n ds e ctheta are the roots of the equation a x^2+b x+c=0 , then |s e ctheta-t a ntheta|=(sqrt(b^2-4a c))/(|a|) b. |s e ctheta-t a ntheta|=(sqrt(b^2+4a c))/(|a|) c. a^4+b^2(-4a c+b^2) d. b^4=a^2(4a c+a^2)

If sintheta=(a^2-b^2)/(a^2+b^2), find the value of t a ntheta,\ s e ctheta\ a n d\ cos e ctheta

If cottheta-t a ntheta=s e ctheta , then theta is equal to 2npi+(3pi)/2, n Z b. npi+(-1)^npi/6,\ n Z c. npi+pi/2, n Z d. none of these

If alpha a n d beta are the solutions of the equation at a ntheta+bs e ctheta=c , then show that tan(alpha+beta)=(2a c)/(a^2-c^2)

Prove the following identity: (t a ntheta+s e ctheta-1)/(t a ntheta-s e ctheta+1)=(1+sintheta)/(costheta)
