Основное тригонометрическое тождество гласит:

sin^2\alpha +cos^2\alpha =1, отсюда

sin^2\alpha +24+cos^2\alpha =sin^2\alpha +cos^2\alpha +24=1+24=\boxed{25}

I was very serious about a career ingymnastics when I was in the 4th form. But then I broke my arm and doctors didn't let me to go in for gymnastics. I love to listen to the modern music and dance. I dance a lot and I hope I am good at it. I also love swimming. I always swim in the Black sea when I visit my parents.I would like to tell you about my family. There are five people in our family. My father's name is Mikhail Evgenyevich. He is a mathematician by education but works at a bank now. My mother's name is Natalya Yakovlevna.

I did well in all the subjects but my favourite subjects at school were Computer Science and English. I also enjoyed Geography lessons. I am very interested in learning English because I always wanted to become an economist or a manager at some joint venture. That is why I think it is necessary to know at least one foreign language. Besides, knowledge of foreign languages helps in everyday life.
