Answer» `underset(thetato(pi)/(2))lim (sec theta-tan theta)=underset(thetato (pi)/(2))lim((1)/(cos theta)-(sin theta)/(cos theta))=underset(x to (pi)/(2))lim((1-sin theta)/(cos theta))` `=underset(thetato (pi)/(2))lim(((1-sintheta)cos theta)/(cos^(2)theta))=underset(thetato (pi)/(2))lim((1-sintheta)cos theta)/(1-sin^(2)theta)` `=underset(thetato (pi)/(2))lim(cos theta)/(1+sin theta)=(0)/(1+1)=0` |
