I will be completely honest with you. I ddon't see eye to eye with geometry. I can't determine anything.

I realized the problem with the angles later. With that picture I had no problem doing it. In the solutions was essentially the same thing but the coordinate system made it very confusing. Thank you very much

X/sin(γ) = 13/sin(α) X/sin(δ)= 13/sin(β) That is only possible if γ=δ and α=β I hope the pic is understandable. EDIT: Also.. I'm on the phone so it's a bit hard to write

Is this enough?

Homework Statement Inside of a square ABCD exists a point M such that |MA|=7 cm, |MB|=13 cm and |MC| = 17 cm. Calculate the area of the square Homework EquationsThe Attempt at a Solution After a lot of formula searching I went and looked at the solution, there they proved that the point M i on...

Thank you but I think it should be said. The problems I am solving are much easier than any olympiad problems.

I found the last book, and it is perfect, thank you

I checked the book and I think I should add another example for better understanding. Determine a maximum and a minimum of the function: f(x)=√(sin4(x)+4cos2(x)) - √(cos4(x) + 4sin2(x))

Hi As the title suggests, I'm looking for a math book that has some competition-style problems in it, with explanations on how to solve them. I have found numerous of other competitions online but the explanations are very not understandable for me. I am NOT talking about international...

Hello everyone, I'm a 3rd grade high school student and very interested in math, physics and chemistry. I'm currently learning vector calculus and electricity. I hope that I will learn what I need for competitions here and I also hope that no matter that I don't have great knowledge I will be...
