Q:
The construction of a tangent to a circle given a point outside the circle can be justified using the second corollary to the inscribed angle theorem. An alternative proof of this const... | 677.169 | 1 |
In \(\triangle ABC\), what is the maximum value of \(\cos A + \cos B + \cos C\)?
I have solved the counterpart of this question with sin instead of cos. I used Jensen's inequality to get the result that the maximum occurs at A = B = C = pi/3. However, as the concavity of y = cos x changes at x = pi/2, Jensen's inequal... | 677.169 | 1 |
minimum value of abc-(a+b-c)(a+c-b)(b+c-a)?
You may find the following information useful:
1. Let a=x+y, b=y+z, c=x+zLet $a, b, c$ be positive numbers. We want to find the minimum value of $abc-(a+b-c)(a+c-b)(b+c-a)$.
We can write this expression as follows:
$$abc-(a+b-c)(a+c-b)(b+c-a) = abc - (s-a)(s-b)(s-c)$$
where $... | 677.169 | 1 |
Activities to Teach Students to Identify Medians, Altitudes, Angle Bisectors, and Perpendicular Bisectors

Tangent to a Circle at a Point
In general, the word "tangent" simply means " to touch ". For example, when a bicycle moves along a road horizontally then the road becomes the tangent at each point when wheels roll on it.

Music Spiral
My name is Clark. I build musical instruments as a hobby and am building a stringed instrument that requires a spiral shaped gear. To generate this gear I need the geometry for the spiral (I can add the teeth). I have attempted to express the problem in the simplest way that I can. I have also attached a ... | 677.169 | 1 |
