How to solve simultaneous equations using graphs. How much is each ticket? Draw a bar to represent one adult and two children’s tickets. Let’s call the adult ticket 𝑦 and the child ticket 𝑥. Another ...

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

The characteristic functions satisfying (2) below are proved to be essentially the semi-stable laws. Auxiliary simultaneous integral equations are studied in Theorems 1, 2, 2' and 3. The final form of ...
