" (iii) "cos theta+sec theta=(5)/(2)quad (3 pi

Choose the correct answer in each of the following questions: If (cos theta + sec theta) =(5)/(2) " then " (cos^(2)theta + sec^(2)theta)=?

Prove that: sec((3 pi)/(2)-theta)sec(theta-(5 pi)/(2))+tan((5 pi)/(2)+theta)tan(theta-(3 pi)/(2))=-1

Prove that sec((3pi)/2-theta)sec(theta-(5pi)/2)+tan((5pi)/2+theta)tan(theta-(3pi)/2)=-1

Prove that: "sec"((3pi)/2-theta)"sec"(theta-(5pi)/2)+t a n((5pi)/2+theta)"tan"(theta-(3pi)/2)=-1.

Prove that sec((3pi)/2-theta)sec(theta-(5pi)/2)+tan((5pi)/2+theta)tan(theta-(3pi)/2)=-1

Prove that: "sec"((3pi)/2-theta)"sec"(theta-(5pi)/2)+t a n((5pi)/2+theta)"tan"(theta-(3pi)/2)=-1.

sqrt((1-sin theta)/(1+sin theta))={sec theta-tan theta, if -(pi)/(2)

Min value of a sec theta+b cos theta is for [theta in(-(pi)/(2),(pi)/(2))]
