if t=0, we have x<8 y<8 z<8 x+y<8 so, 0<x<8, y<8-x, z<8 List them all. If t=1, change the 8's to 7's in the first 3 conditions. And so on, up to t=7: x<1 y<1 z<1 x+y<8 (x,y,z,t) = (0,0,0,7) Don't see the point of the exercise, but there it is.

I assume you mean 4 - (1/b) < 3/b Add 1/b to both sides and the < stays the same direction 4 < 4/b 1 < 1/b Multiply both sides by b. Different rules apply about the < sign depending upon the sign of b. If b is positive, b < 1. So 0<b<1 is one solution ...

Well, it will surely be a piecewise function, so d(t) = 3t for 0<=t<=1 3+2(t-1)/3 for 1<t<=4 5 for 4<t<=7 5+5(t-7)/3 Just look at the slope of each piece, and add the offset where it starts.

for Knights
Just a final note. Since the 3rd altitude h is bounded by 1/a + 1/b <= 1/h <= 1/a - 1/b where a < b, the limiting case where a=b (an isosceles triangle) shows that 1/a+1/a <= 1/h <= 1/a - 1/a 2/a <= 1/h <= 0 shows that h >= a/2, and may grow without bound.
