" 17."lim_(theta rarr pi)(sec theta-tan8)

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

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

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

Evaluate the following limits : Lim_(theta to pi/2 ) (sec theta - tan theta )

Given that lim_(theta rarr 0) (sin theta)/theta = 1 and lim_(theta rarr 0) cos theta = 1 Evaluate lim_(theta rarr pi/2) (cot theta)/(pi/2 - theta)

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

Evaluate the following : lim_(theta rarr 0)(sin3 theta)/(tan2 theta) .

Evaluate the following : lim_(theta rarr 0)(sin4 theta)/(tan3 theta) .

lim_(theta rarr 0) ("cosec" theta - cot theta)/(theta) is :
