Elena Vasilyevna's Bezik website is a useful resource for preparing for the Unified State Exam in mathematics

Here it is - a real assistant for those who want to cope with task number 13 on the Unified State Exam in mathematics. Websitebezikev. rubelongs to mathematics teacher Elena Vasilyevna Bezik. There are many examples of solutions to trigonometric equations that appear in exam papers. Yes, yes, exactly the kind where you need to find roots on a segment or simply solve an equation as written in the condition.

You can view several tasks at once. For example, equations like cos3x sin3x cos(π3) cos(12x + 3π2). Already interested? And here's another: sin²(x4 + π4)sin²(x4 - π4) 0.375sin(-π4). The mere sight of these expressions can be intimidating, but here everything is explained step by step. Directly and without further ado - read on, and everything will become clear.

Don't think that this is just cheating. Each solution is accompanied by an explanation of the steps. It is important not only to get the answer, but also to understand how it turned out. What is especially useful is that there are sections indicating intervals - like [-3π4; -π4] or [-2π; 3π2]. These points often confuse students. And here the emphasis is on them.

What else can be found on the site?

• Analysis of task 13 from the Unified State Exam in mathematics
• Solutions for different options
• Exercises with different trigonometric functions: sine, cosine, their sums and products
• Methodology for solving complex equations through identity transformations
• Practice for those who want to practice skills before exam

The site is clearly focused on preparing for the unified state exam. There are even links to demos on computer science and mathematics - although these are not the focus. But still, if you need to test yourself on your knowledge of formulas or the structure of tasks, you will also find something suitable here.

The interface is simple but effective. There are no unnecessary pictures, no advertising that gets in the way. Just text, tasks, solutions - all you need. You can read it in the evening when you want to repeat the topic. Or in the morning - to refresh your memory before the test. The main thing is not to miss a single step.

Who is the author of the site?

Elena Vasilyevna Bezik is a mathematics teacher, apparently with extensive experience. She doesn't just give answers, but shows the train of thought. This is important. Especially when you decide for yourself and then check. She also shares materials on the OGE and thematic planning. Not everyone does this. Many people hide their materials. And here is open work.
