`cos^(2)theta+sin theta=1`

cos^(2)theta-sin theta.cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

cos^(2)theta-sin theta*cos theta-(1)/(2)=0

Solve for theta : cos^2 theta-sin^2 theta=1/2,0 यदि cos^2 theta-sin^2 theta=1/2,0

Solve the following equation: cos^(2)theta-sin theta cos theta-(1)/(2)=0

If theta lies in the first quadrant and cos^2 theta-sin^2 theta=1/2 , then the value of tan^2 theta+sin^2 3 theta is : यदि theta पहले चतुर्थाश में स्थित है और cos^2 theta-sin^2 theta=1/2 है, तो tan^2 theta+sin^2 3 theta का मान ज्ञात करें |
