If ` A B C` having vertices `A(acostheta_1,asintheta_1),B(acostheta_2asintheta_2),a n dC(acostheta_3,asintheta_3)` is equilateral, then prove that `costheta_1+costheta_2+costheta_3=sintheta_1+sintheta_2+sintheta_3=0.`

If DeltaABC having vertices A (acostheta_1, asintheta_1), B (acostheta_2, asintheta_2), and C (acostheta_3, asintheta_3) are equilateral triangle, then prove that cos theta_1 + costheta_2 + cos theta_3 = 0 and sintheta_1 + sintheta33

prove that- (sintheta+1-costheta)/(costheta-1+sintheta)=(1+sintheta)/costheta

sqrt(3)costheta+sintheta=2

If (a costheta_1,asintheta_1),(acostheta_2,a sintheta_2) , and (acostheta_3a sintheta_3) represent the vertces of an equilateral triangle inscribed in a circle. Then.

Prove that : (1+sintheta)/(costheta)+(costheta)/(1+sintheta)=2sectheta

If costheta-sintheta=sqrt(2)sintheta , then prove that: costheta+sintheta=sqrt(2)costheta

If sintheta-costheta=1 ,then find sintheta.costheta

If sintheta_1+sintheta_2+sintheta_3=3," then "costheta_1+costheta_2+costheta_3 is equal to

If sintheta_(1)+sintheta_(2)+sintheta_(3)+sintheta_(4)=4 , then what is the value of costheta_(1)+costheta_(2)+costheta_(3)+costheta_(4)= ?

If (sintheta+costheta)/(sintheta-costheta)=3 and theta is an acute angle, then the value of (3sintheta+4costheta)/(8costheta-3sintheta) is
