Question

( frac{frac{1}{cos theta / 2} sin theta / 2}{frac{1}{cos ^{2} theta}+sin ^{2} theta / 2-sin ^{2} frac{1}{1} sin theta}=frac{frac{2}{3}}{frac{4}{g}} )
( frac{9-4-451 ln theta}{4 cdot sin theta-5} )
( sin ^{2} frac{theta}{cos theta-sqrt{1+sin ^{2} a}} frac{sin ^{2} x}{sqrt{1-frac{2 pi}{1-6}}} )

# B-3. If tano + seco = then seco is
