Modifiez les unités en une expression d'axe.

1. Définissez une variable suite et une fonction avec des unités.

2. Tracez la fonction.

Les valeurs des graduations sont affichées en termes d'unités de base du système d'unités que vous utilisez, quelles que soient les unités entrées.

3. Modifiez les unités utilisées pour le tracé de l'expression de l'axe des y en supprimant l'abréviation de mètre "m" de l'emplacement réservé à l'unité et en insérant l'abréviation de pouce in dans l'emplacement réservé vide.

Les courbes représentent des nombres équivalents. Par exemple, le deuxième point sur la première courbe se trouve à 79 in = 2 mètres. Sur la deuxième courbe, il se trouve à 20 * 0.1 m = 2 mètres.

5. Insérez deux marqueurs horizontaux au niveau des deux points de données ci-dessus.
