24, Prove that; S6¢9+tanb-1_ 0080tanO-secO11 1-sind

Answer»

LHS:- tan theta + sec theta - (sec²theta - tan² theta /tan theta - sec theta + 1 =( tan theta + sec theta)(1- sec theta + tan theta )/tan theta +1 - sec theta =tan theta +sec theta =sin theta / cos theta + 1/cos theta = 1+ sin theta / cos theta ⁼sec theta+ tan thetaLHS = RHS Hence proved
