Автор ответа: MaxLevs

$5SinX + CosX = 0$ Длим все выражение на CosX
$5TgX+1=0$
$TgX = - \frac{1}{5}$
$X = - Arctg( \frac{1}{5} ) + pi *n= - Arctg( 0,2 ) + pi*n$

MaxLevs: Точно, прошу прощения.. 3 часа ночи, совсем вылетело из головы

MY HOUSE
I would like to tell you all about my home. Firstly, I must tell you that I live in Pyatigorsk. It's a very fascinating town with old traditions.
We have sprung up around the city's old centre. We live in one of such newly built areas. Though it isn't quite close to the town centre, it's only seven stops by tram from the town's main street.
We moved into our new flat five years ago. It's a four-room flat on the third floor of a nine-storied block of flats. Certainly there are all modern conveniences in our flat. It's fairly cosy. The layout is good. The rooms are light, though not very large. It's quite a modern looking flat with two balconies looking out on the park in front of the building. Every time I walk into my flat, I feel an immediate sense of warmth and security.
Our sitting room is quite a big room, about 20 square metres. My mother doesn't like much furniture in the flat. So in the sitting room there are two comfortable chairs and a sofa, a coffee-table, a television set and a video in the corner of the room and a piano. Of course, there is a carpet on the floor. We usually relax, watch television, listen to music in the sitting-room or have dinner on special occasions. We have two pictures on the wall of our room. They are nice copies of my favourite painting by Levitan. They make the room comfortable.
I am happy to have a room of my own. It's the smallest room in the flat but I try to keep it tidy and cosy. There is a single-bed, a desk, a personal computer, a stereo-system, a big bookcase and a wardrobe in my room. There is a little rug on the floor. There are some posters of my favourite pop star above the bed.
You may be surprised to hear when I tell you that the most popular and favourite place with all of us is a kitchen. We spend most of our time in the kitchen, not eating in fact, we like just to sit and talk there.
Our kitchen is comparatively large and looks the usual modern kitchen you can see in many other homes. The air is usually filled with the delicious smells of my mother's cooking. There is a cooker, a fridge, a washing machine, a dishwasher, a microwave, a kitchen table with four stools and some cupboards in it. There are some lovely pictures on the walls. We have regular meals in the kitchen. My family likes to sit chatting for hours after work in the evenings. But I have to bring a chair and take it away when the whole family is at table. But it's not much trouble.
Ah, yes, I haven't mentioned the hall or as we call it the cor¬ridor. It's long but slightly narrow. Or perhaps it looks narrow to me because my brother Oleg keeps his bike in it.
When my friends come to my house they often describe it as a dream house, but to me it's just 'home sweet home."
