lim_(theta rarr pi/2)(sec theta-tan theta)/(pi-2 theta)

cos((3 pi)/(2)+theta)*cos(2 pi+theta)=

lim_(theta to (pi)/(2)) ((pi)/(2)-theta)/(cot theta) is equal to

A function f(theta)=sin^(2)theta+3sin theta cos theta+5cos^(2)theta is defined AA theta in R . Another function g(theta)=f((pi)/(2)-theta) at the point theta where f(theta) is minimum, then thevalue of (1)/(g(theta)) is

lim_(theta rarr(pi)/(2))(sec theta-tan theta)/(pi-2 theta)

If tan((pi)/(2) sin theta )= cot((pi)/(2) cos theta ) , then sin theta + cos theta is equal to
