dy 4. dx Inx ... starting point (4.2, 7.6) ... use 3 steps to estimate y at x=5.1 dy sin x 5. ... starting point (1.2, -0.6) ... use step size 0.1 to estimate y at x=1.5 dx X 6. [*] dy = xy ... starting point (0.2, 1.4) ... use 3 steps to estimate y when x=1.1 [note that you dx must do one step at a time]
