Section 6.1, Problem 34
This page explains some Maple commands that you may find helpful for problems such as #34 from section 6.1.
Tip: To get help about any command, type a question mark followed by the command name and press enter. For example, to get help about the solve command, type ?solve[ENTER]
Problem 34 asks us to find the point of intersection of two curvs, which amounts to solving
for x. We could use the solve command, but then we get a messy expression with lots of fractions and roots, as shown below.

Instead, we should use the fsolve command, which will give us a decimal number. (The f stands for floating-point, which is another term for a decimal number.) The syntax is fsolve( equation , variable ).

We can also use the plot command to graph the equations. The syntax is
where
and
are the equations we want to graph, and a and b are the lower and upper bounds of the plot window. See the example below.

We can even ask Maple to evaluate the integral for us. The syntax is integrate( equation, x=a..b) where again a and b are the bounds of integration. See the example below.
