$tg(3\pi+\alpha )+\frac{Sin(\frac{\pi }{2}+\alpha)}{1-Cos(\frac{3\pi }{2}-\alpha)} =tg\alpha +\frac{Cos\alpha}{1+Sin\alpha}= \frac{Sin\alpha}{Cos\alpha}+\frac{Cos\alpha }{1+Sin\alpha}=\frac{Sin\alpha+Sin^{2}\alpha+Cos^{2}\alpha}{Cos\alpha(1+Sin\alpha)}=\frac{Sin\alpha+1 }{Cos\alpha(1+Sin\alpha)} =\frac{1}{Cos\alpha}$

tga+cosa/(1+sina)=sina/cosa+cosa/(1+sina)=

приводя все к общему знаменателю

=(sina(1+sina)+cos^2a)/(cosa(1+sina))=(sina+sin^2a+cos^2a)/(cosa(1+sina))=

=(sina+1)/(cosa(1+sina))=1/cosa
