The fundamental note


1) ABZP is a rectangle and ABCD and CXYZ are squares whose areas add up to 1 .

Maximum possible area of the rectangle ABZP-


2) Let A , B and C be 3 circles lying in the same quadrant each touching both the axes . Suppose also that A touches B and B touches C . If the area of the smallest circle is 1 unit , then area of largest circle is -


3) Consider an equilateral triangle ABC with side 2.1 cm. You want to place a number of smaller equilateral triangles , each with side 1 cm , over the triangle ABC , so that triangle ABC is fully covered. What is the minimum number of smaller triangles needed

5) For all g:RR 01(tg(t))2dt is positive\displaystyle For~ all~ g: R \to R ~ \int_{0}^{1} (t - g(t))^2 dt ~is~ positive

6) f(x) is a non-negative continuous function such that f(x)+f(12+x)=1f(x) + f(\dfrac{1}{2} + x) = 1 for all x,0x12 x , 0 \leq x \leq \dfrac{1}{2} , then 01f(x)dx=\displaystyle \int_{0}^{1} f(x)dx =

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
