AI Thread Summary
To solve the formulas given specific variable values, substitute the known values into the equations. For the example provided, with x = y * z and initial values y = 1 and z = 1, calculate x as 1 * 1, resulting in x = 1. Next, update z by adding 1 to its current value, changing z from 1 to 2. The value of y remains unchanged at 1. Thus, the final values are x = 1, y = 1, and z = 2.

Hi how would you solve formula such as this?

example

x=1
y=1
z=1

x = y * z
z = z + 1

x=?
y=?
z=?

(Wave)You just have to replace the values of $y,z$ .

So you have to calculate $x=y \cdot z$ and you know that $y=1, z=1$. Therefore $x=1 \cdot 1=1$.

Then $z=z+1$.We know that $z=1$, so $z=1+1=2$.
The value of $y$ doesn't change , so $y=1$.
 
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...
