cos(2п-a)/sin(п/2+a)=tg40-tg5/1-tg40*tg5

1.cos(2п-а)=cos(a)

2.sin(п/2+a) =cos(a)

3.tg40-tg5/1-tg40*tg5=tg(40+5)=tg45

и того:

cos(a)/cos(a)=tg45

tg45=1

1=1 - верно

The entertainment is an important part of the modern life. The concept of «entertainment» includes not only a pretty pastime, but also a passion of art, movies, music, dancing, reading, and sports. The development of the outlook is impossible without reading, hobbies, a passion of music or the theater, opera, ballet… A visit to the cultural events such as exhibitions, presentations, and primes is an integral part of the intelligent person’s life. As for me, despite the fact that most of my time is busy with the study, I also find the time for my hobbies. There are: studying of foreign languages, swimming and music. Without music and sports I cannot imagine my life. Among the music styles I like pop, alternative rock and club music. I’m not some of those people who used to have a rest, lying on the sofa. I am an adherent of the active recreation. After a hard day the best way to release tension is to swim in the pool. The cinema as a form of the entertainment is firmly included in people’s lives. Despite of busy schedule, many people keep an eye on release of the film masterpieces and do not miss an opportunity to visit the cinema. In my opinion, the entertainment is not a waste of time. Entertainment is a source of cheerfulness and necessary energy for the new achievements.
