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

Prove: (cos ec theta-sec theta)(cot theta-tan theta)=(cos ec theta+sec theta)(sec theta cos ec theta-2)

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

Prove the following identity: ((1)/(sec^(2)theta-cos^(2)theta)+(1)/(cos ec^(2)theta-sin^(2)theta))sin^(2)theta cos^(2)theta=(1-sin^(2)theta cos^(2)theta)/(2+sin^(2)cos^(2)theta)

(tan theta)/(1+cot theta)=(tan theta-1)/(2-cos ec^(2)theta)
