Question

exe o
( (m+cos A)left(frac{sin 2 x+cos ^{2} x}{sin A cdot cos n)}right. )
( lim _{A}+cos x )
dind cdot cerse
( frac{ln 11}{lim _{x} cos x}+frac{operatorname{cosex}}{Delta x ln alpha cdot cos x} )
( operatorname{lec}_{a}+operatorname{cosec}^{2} alpha )

# (sin a + cos a) (tan a + cot a) = sec a + cosec a L ael.
