(1-cos(2x))/(6sinx)=(cos²x+sin²x-cos²x+sin²x)/(6sinx)=2sin²x/(6sinx)=sinx/3.
∫(sinx/3)dx=-cosx/3+C.

текст

1. Most parents tell their children not to play with their food. A group of musicians in Austria obviously didn't listen! The Vienna Vegetable Orchestra, which was founded in 1998, uses fresh vegetables to make music. 2. They choose only the freshest vegetables from local markets for their instruments. Moreover, the instruments are made an hour before the show. 3. "Fresh vegetables produce high-quality sounds. 4. Plastic-packed vegetables do not make good instruments," they say. Each vegetable can be used in many different ways. Carrots are made into flutes, leeks into violins and pumpkins into bass drums. Combinations of vegetables are also used together to create instruments. For example, they can make a trumpet by using a cucumber for the body, a carrot for the mouthpiece and a pepper for the trumpet's bell. The sound of each instrument depends on the quality of the vegetables and the temperature on stage. The orchestra is constantly working on developing new instruments. The orchestra's musical repertoire ranges from classical to electronic. 5. They play about 20 to 30 concerts a year. This one-of-a-kind musical group is also environmentally-conscious since all the instruments are bio-degradable. At the end of each performance, the vegetables are made into a delicious soup for the audience to eat. The whole experience is something that all your senses can enjoy!
