+ Answer: False
+
+#. What command is used to get individual plots separately?
+
+ Answer: Figure
+
+#. Which figure is closed after the following commands are run?
+
+::
+
+ x = linspace(0, 50, 500)
+ figure(1)
+ plot(x, sin(x), 'b')
+ figure(2)
+ plot(x, cos(x), 'g')
+ xlabel('x')
+ ylabel('cos(x)')
+ close()
+
+ Answer: Figure 2
+
+#. Describe the plot obtained by the following commands::
+
+ x = linspace(0, 50, 500)
+ subplot(2, 1, 1)
+ plot(x, sin(x), 'b')
+
+Answer: A figure window with space for 2 plots one below the other is
+ obtained. The sine plot with blue line appears in the first row.
+
+#. Describe the plot obtained by the following commands::
+
+ x = linspace(0, 50, 500)

+
+ Answer: 2 plots one below another. sine in blue on first row. cosine
+ in green in the second row.
