(1-cosa)/cosa+sina/cosa=(1-sina+sina)/cosa=1/cosa
2
1/(1+cosa)+1/(1-cosa)=(1-cosa+1+cosa)/(1-cos²a)=2/sin²a
3
cos²b/sin²b*(-sin²b)+1=-cos²b+1=sin²b
4
(sinb/cosb+1):(1+cosb/sinb)=(sinb+cosb)/cosb*sinb/(sinb+cosb)=
=sinb/cosb=tgb

1(1-cosa)/cosa+sina/cosa=(1-sina+sina)/cosa=1/cosa
2
1/(1+cosa)+1/(1-cosa)=(1-cosa+1+cosa)/(1-cos²a)=2/sin²a
3
cos²b/sin²b*(-sin²b)+1=-cos²b+1=sin²b
4
(sinb/cosb+1):(1+cosb/sinb)=(sinb+cosb)/cosb*sinb/(sinb+cosb)=
=sinb/cosb=tgb
