MHB Determine the approximate values of sinθ and cosθ from the diagram below

AI Thread Summary
To determine the approximate values of sinθ and cosθ from the diagram, one must recognize that if the points are on the unit circle centered at the origin, then x equals cos(θ) and y equals sin(θ). The specific values depend on the angle θ, which is not indicated in the diagram. A suggestion is made that θ could relate to the angle of symmetry in the letter "o" of the Google logo. Without a clear indication of θ, precise values cannot be established. Understanding the relationship between the angle and the unit circle is essential for accurate calculations.

Re: Determine the approximate values of sinθ and cosθ from the digram below

If your points are on the unit circle centred at the origin, then [math]\displaystyle \begin{align*} x = \cos{(\theta)} \end{align*}[/math] and [math]\displaystyle \begin{align*} y = \sin{(\theta)} \end{align*}[/math].

This, of course, depends on what $\theta$ is since it is not marked on the diagram. Maybe it's the angle made by the axis of symmetry of the letter "o" in the Google logo (which is typeset in the Catull font). (Smile)

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
