Penn State MATH 141, Calculus with Analytic Geometry II, is the second course in Penn State's calculus sequence for science, engineering and related fields. Worth 4 credits, it builds on MATH 140 with new functions, new integration techniques and infinite series. This guide maps every MATH 141 topic to practice so you can learn each one by solving problems with instant feedback.
What Penn State MATH 141 covers
The bulletin lists the MATH 141 topics in order: logarithms, exponentials and inverse trigonometric functions; applications of the definite integral and techniques of integration; sequences and series; power series and Taylor polynomials; and parametric equations and polar functions.
Most of that is a standard Calculus 2 course. The first unit is the exception: calculus of e^x, \ln x and inverse trig functions, which many universities teach in Calculus 1. If you are coming to Penn State with credit from elsewhere, check that you have seen these.

Example problems at the MATH 141 level
1. An inverse trig derivative. Since \frac{d}{dx}\arctan x = \frac{1}{1 + x^2}, the chain rule gives
2. Partial fractions. Evaluate \int \frac{1}{x(x + 1)}\,dx. Write \frac{1}{x(x+1)} = \frac{1}{x} - \frac{1}{x + 1}, so
3. A Taylor polynomial. The degree 3 Maclaurin polynomial of e^x is
so e^{0.1} \approx 1 + 0.1 + 0.005 + 0.000167 \approx 1.10517.
How to do well in Penn State MATH 141
- Master the first unit fast. Log, exponential and inverse trig derivatives show up inside every later integral. The logarithmic differentiation rule is worth learning early.
- Practice choosing a technique. The choosing a strategy lesson mixes problems the way exams do.
- Learn a decision path for series. Start with the nth-term test, then geometric and p-series, then the ratio test.
- Keep the formula sheet close for common Maclaurin series, and take timed practice exams.
- Review common calculus mistakes before each midterm.
Tip: when a series has factorials or powers of n in the exponent, try the ratio test first. It usually settles the question in two lines.
