What You'll Learn

A full semester of calculus iii โ€” completed at your own pace, with no deadlines or fixed class times.

Learning Outcomes

What You'll Be Able to Do

  • Perform vector operations in 2D and 3D space โ€” including dot product, cross product, and projections โ€” and apply them to geometric problems involving lines, planes, and quadric surfaces
  • Analyze vector-valued functions using calculus to compute derivatives, integrals, arc length, curvature, and model motion in space
  • Compute and interpret partial derivatives, gradients, and directional derivatives for multivariable functions, and apply the chain rule and linear approximation
  • Solve constrained and unconstrained optimization problems for multivariable functions using critical point analysis and Lagrange multipliers
  • Evaluate double and triple integrals in Cartesian, polar, cylindrical, and spherical coordinates, and apply them to compute area, volume, mass, and center of mass
  • Compute line integrals of scalar and vector fields, apply the Fundamental Theorem for Line Integrals, and use Green's Theorem to relate line and double integrals
  • Evaluate surface integrals over parametric and explicit surfaces, compute flux integrals, and apply Stokes' Theorem and the Divergence Theorem

FAQ

Common Questions Answered.

Everything you need to know about Calculus III โ€” credits, grading, transfer, and how it compares to traditional options.

What is Calculus III?
Multivariable calculus โ€” vectors, space curves, partial derivatives, multiple integrals, and vector calculus including Green's, Stokes', and the Divergence Theorems. It is Math 365.
Do I need Calculus I and II first?
Yes. Calculus III assumes solid single-variable differential and integral calculus.
Is this the same as multivariable calculus?
Yes โ€” Calculus III, multivariable calculus, and vector calculus generally refer to the same course content.
What comes after the Calculus 3 course?
Typically Differential Equations and Linear Algebra in most engineering and mathematics sequences.
How is Calculus 3 graded?
Subchapter quizzes, one assignment, and a 100-question final exam. 70 or above is required to pass.
How long does Calculus 3 take to complete?
46 contact hours. Most students take 28โ€“30 days, though this is a demanding course.
Will my engineering program accept it?
Many engineering programs accept transferred math credit, though some want the calculus sequence taken in residence โ€” check Find My College or book a free advisor call and we'll confirm your school in minutes.
Does the Calculus 3 course include video lessons?
The course provides written lessons with worked examples on the UPI Study platform.
Is there a CLEP exam for Calculus 3?
No โ€” CLEP Calculus covers only Calc 1 material, so a transferable course is the main self-paced route to multivariable calculus credit.
What does Calculus 3 cover?
Multivariable calculus โ€” vectors, partial derivatives, multiple integrals, and vector calculus including line and surface integrals.
Do I need Calculus 2 before Calculus 3?
Yes โ€” series, integration techniques, and Calc 2 fluency are assumed throughout.
Is Calculus 3 accepted for engineering and math majors?
Often yes, but STEM programs sometimes require the calculus sequence in residence โ€” your registrar can confirm the equivalency in minutes.
How hard is Calculus 3 compared to Calc 1 and 2?
Many students find it conceptually different rather than harder โ€” visualizing three dimensions replaces the heavy algebraic grind of Calc 2.
