" 1.If "tan(theta)/(2)=cos ec theta-sin theta," then find "cos^(2)(theta)/(2)

if tan((theta)/(2))=cos ec theta-sin theta then cos^(2)((theta)/(2))

If tan((theta)/(2))=(cos ec theta-sin theta) then tan^(2)((theta)/(2))=

If tan((theta)/(2))=cos ec theta-sin theta then the numerical value of (cos^(2)theta)/(2)=

If (tan theta)/(2)=cos ec theta-sin theta, then the numberical value of cos^(2)((theta)/(2)) is

Prove: (cos ec theta+sin theta)(cos ec theta-sin theta)=cot^(2)theta+cos^(2)theta

If 3cos theta-4sin theta=2cos theta+sin theta then find tan theta

If sin theta=cos theta then 2tan theta+cos^(2)theta=

Evaluate the following determinants: (b) |(cos theta, -sin theta),(sin theta, cos theta)| = cos theta (cos theta) - sin theta(-sin theta) = cos^(2) theta + sin^(2) theta = 1

(cos ec theta+sin theta)/(cos ec theta-sin theta)=(5)/(2), find value of sin theta

If sin theta+cos ec theta=3, then sin^(2)theta+cos ec^(2)theta=
