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

lim_(theta rarr(pi)/(4))(1-tan theta)/(1-sqrt(2)sin theta)

the value of lim_(x rarr(pi)/(2))(sec theta-tan theta)

int_(0)^((pi)/(2))(sec theta-tan theta)d theta

The value of lim_(theta rarr(pi)/(2))(sec theta-tan theta) equals

Prove that lim_(theta rarr(pi)/(2))(2cos theta)/(pi-2 theta)=1

evaluate lim_(theta rarr(pi)/(4))(sqrt(2)-cos theta-sin theta)/((4 theta-pi)^(2))

lim_(theta rarr0)(3tan theta-tan3 theta)/(2 theta^(3))

Putting x = theta- (pi) / (4) prove that lim_ (theta rarr (pi) / (4)) (sin theta-cos theta) / (theta- (pi) / (4)) = sqrt (2)

lim_(theta rarr pi/2) (pi/2- theta)/(cot theta) =
