This line-art explains the bisection method, a classic numerical root-finding algorithm. At the top, a function curve crosses a horizontal baseline, and two stems at the ends show one value below zero and one above, which guarantees a root lies between them. Below, a stack of bars shows each iteration: a small cut mark sits at the midpoint of every bar, the half that still contains the sign change is drawn solid, and the rejected half is dashed. Each new bar is exactly the kept half of the one above, so the bracket shrinks by a factor of two every step. A dotted guide drops from the crossing point through every level to a final marker, showing the solution stays trapped inside the shrinking bracket. Method vectors

Euler's method, the simplest numerical technique for solving an ordinary differential equation from a known starting value. A solid dot marks the initial condition. From there, a chain of straight segments advances in equal-width steps, each one following the slope at the point where it begins, with hollow rings marking every computed estimate. Evenly spaced ticks along the horizontal axis show the constant step size h. A faint dashed curve traces the exact solution for comparison: the two start together, then separate as the straight steps overshoot the bend, so the widening gap between them makes the accumulating truncation error easy to see.
