Course Trivium
for Engineering Calculus I
Enumerated here are the calculations and tasks
that should become routine to students in this course.
Each is stated as a skill to master, having a well-defined goal
and suggesting the exercises to perform to practice the skill.
It is worth a student’s time to become proficient at doing these tasks
so as to not be impeded thinking about more compelling mathematics.
-
Given a function and two points in its domain,
compute the average rate of change
of the function between those points.
I.e. determine the slope of the secant line
between two points on a function’s graph.
-
Given either a formulaic or graphical presentation of a function \(f\)
and some point \(x_0\) in its domain, determine whether or not the limits
\[ \lim_{x \to x_0^{-}} f(x) \qquad \lim_{x \to x_0} f(x) \qquad \lim_{x \to x_0^{+}} f(x) \]
exist, and if they exist numerically approximate their value
or determine their exact value if possible.
-
Given either a formulaic or graphical or narrative description of a function \(f,\)
determine whether or not the limits
\[ \lim_{x \to -\infty} f(x) \quad\qquad \lim_{x \to \infty} f(x) \]
exist, and if they exist numerically approximate their value
or determine their exact value if possible.
-
Given either a formulaic or graphical or narrative description of a function,
determine whether or not the function is continuous on its domain.
-
Given a formula for a function expressed as
a sum, difference, product, quotient, or composite
of algebraic and trigonometric functions,
write a formula for its derivative.
-
Determine a function’s derivative from the definition:
\[ \frac{\mathrm{d}}{\mathrm{d}x}f(x) = \lim\limits_{h \to 0} \frac{f(x+h) - f(x)}{h}\,, \]
-
Given a function and a point in its domain
around which the function is differentiable,
compute the instantaneous rate of change
of the function at that point.
-
Given a function and a point in its domain
around which the function is differentiable,
determine an equation of the line tangent to
the graph of the function at that point.
-
Given a multivariable equation consisting of
sums, products, quotients, or composites
of algebraic and trigonometric functions,
write down a implicit formula for the derivative
of any dependent variable in that equation
with respect to any variable on which it depends.
-
For any function expressible piecewise
in terms of sums, products, quotients, or composites
of algebraic and trigonometric functions,
determine its extreme values and inflection points
and any intervals on which it is increasing/decreasing
or accelerating/decelerating,
and from this information accurately sketch the graph of the function.
-
Use Newton’s method to approximate the value to any precision
of the root of any function that is differentiable around that root.
-
Express the value of a definite integral as a limit of a Riemann sum,
and approximate the value to any precision
of that definite integral using the Riemann sum.
-
Determine an antiderivative of any sufficiently simple function
expressible in terms of sums, products, quotients, or composites
of algebraic and trigonometric functions,
and use that antiderivative to calculate the exact value
of the definite integral of the function
according to the Fundamental Theorem of Calculus.
-
Given two sufficiently simple functions
expressible in terms of sums, products, quotients, or composites
of algebraic and trigonometric functions
whose graphs intersect at points with algebraic coordinates,
determine the area of the region bound by those graphs.
-
Compute the volume of any solid whose cross-sections along some axis
have an area describable as an integrable function.
(e.g. solids of revolution).
-
Compute the work being done as some linear, potentially variable, force
is being applied to a potentially variable mass.
