Section 9.3.1 Table Values for Eulars method #24

Open hywelandrews opened 9 months ago

hywelandrews commented 9 months ago

In section 9.3.1 "Carrying out Euler's method by hand" an initial table is provided and a walk through for completing the first 3 rows begins. There appears to be a contradiction in the explained vector value for row 2, where we calculate this value for the vector column as (1, 0.4) but the table is completed as an example with the value (1,0) for v(2).

Either the table is incorrect and should appear as

t s(t) v(t) a(t)
0 (0,0) (1,0) (0, 0.2)
2 (2,0) (1, 0.4) (0, 0.2)
4 (0, 0.2)
6 (0, 0.2)
8 (0, 0.2)

Or the table is correct but the discrepancy for the v(2) value should be explained.
