Nine-point-circle, midpoint of triangle ABC is the triangle and M, N are midpoints of AB and AC. Points W, X are on AB, Y, Z are on AC such that WM = MX, ZN = NY. Let T be the intersection of WY and XZ, prove that T l...

Let $ \angle BAC = \alpha$. **Hint:** Recall that the nine-point circle passes through the midpoint of all sides. Step 1. To show that $T$ lies on the circle, it suffices to show that $\angle MTN = 180^\circ - \alpha$. Step 2. To show that $\angle MTN = 180^\circ - \alpha$, we will show that $\angle...

How can I find the maximum value of $ f(t)=xcos(t)+sin(t)(wyz-wzy)+wx(wxx+wyy+wzz)(1-cos(t))$; I have the function: $f(t)=x cos(t)+sin(t)(wy z-wz* y)+wx(wx x+wy* y+wz* z)*(1-cos(t)).$ Only $t$ is vari...

Hint: $a\sin t+b\cos t=\sqrt{a^2+b^2}\sin(t+\alpha)$ for some $\alpha\in[0,2\pi)$. It's maximum value is $\sqrt{a^2+b^2}$.
