WGU course completion
At a glance
Last updated
C647 Trigonometry and Precalculus (MATH 6321, 2 CUs in the September 2026 WGU catalog) is the shared term-1 math course of both M.A. Mathematics Education tracks, Middle Grades and Secondary, for licensed teachers. Trigonometric functions, identities, and equations, complex numbers including DeMoivre's Theorem, systems of equations, vectors and matrices, and sequences and series, with College Algebra stated as the prerequisite. On the bachelor's path the same material is split across two courses, D667 Precalculus and D889 Trigonometry. Coursework Ninja completes C647 done-for-you, fixed quote in writing first. From $99. Independent of WGU.
Per WGU's published description, C647 covers the knowledge and skills necessary to apply trigonometry, complex numbers, systems of equations, vectors and matrices, and sequences and series, and to use appropriate technology to model and solve real-life problems. The topic list runs degrees, radians and arcs, reference angles and right triangle trigonometry, applying, graphing and transforming trigonometric functions and their inverses, solving trigonometric equations, using and proving trigonometric identities, geometric, rectangular, and polar approaches to complex numbers, DeMoivre's Theorem, systems of linear and nonlinear equations, systems of inequalities, matrix-vector equations, and arithmetic and geometric sequences and series. The catalog states College Algebra is a prerequisite.
Both M.A. Mathematics Education tables carry C647 in term 1: the Middle Grades track and the Secondary track, where it opens the path beside College Geometry and Calculus I. On the undergraduate mathematics education ladder the same material is split into two separate courses, D667 Precalculus (MATH 1040) and D889 Trigonometry (MATH 2110), both of which already have completion pages; the graduate track compresses them into one 2-CU course. Message us the code and where you stand, and we quote a flat price in writing.
Every full package includes the written 6-month guarantee: we finish the remaining CUs under the agreed plan, or you do not pay. Packages: Bachelor's $3,000 · Master's $3,500 · both $5,500 · single assessments from $99.
Coverage
WGU does not publish assessment formats in the catalog. Student communities report a proctored objective assessment (OA) for the graduate trigonometry and precalculus course, consistent with the exam pattern of the precalculus and trigonometry courses on the bachelor's path. We confirm the current format for your catalog year at intake, and the fixed quote covers whichever assessment C647 carries.
The description's core: applying, graphing and transforming trigonometric functions and their inverses, from reference angles and right triangle trigonometry through radians and arcs. The unit circle is the mental model every later topic leans on, and it is where rust shows first.
Solving trigonometric equations and using and proving trigonometric identities. Proofs are the distinctive demand: recognizing which identity collapses an expression, then writing the chain that a grader can follow line by line.
Geometric, rectangular, and polar approaches to complex numbers and DeMoivre's Theorem, the topic bachelor's students meet latest and forget first. Converting between forms and raising complex numbers to powers is standard exam material here.
The description closes across systems of linear and nonlinear equations, systems of inequalities, matrix-vector equations, vectors and matrices, and arithmetic and geometric sequences and series, the precalculus material the calculus courses behind the track assume fluently.
C647 alone is a single from $99. On a remaining list in either M.A. Mathematics Education track it folds into the flat master's package at $3,500, every remaining academic CU under the written 6-month finish guarantee.

Bottlenecks
C647 compresses two undergraduate courses into one and opens both M.A. math tracks, so a slow first month compounds across the whole path. These are the stalls we take over most often.

Per the September 2026 WGU institutional catalog, Trigonometry and Precalculus (MATH 6321, 2 CUs) covers applying trigonometry, complex numbers, systems of equations, vectors and matrices, and sequences and series with appropriate technology: degrees, radians and arcs, reference angles, graphing and transforming trigonometric functions and inverses, solving trigonometric equations, proving identities, complex numbers in geometric, rectangular, and polar form, DeMoivre's Theorem, linear and nonlinear systems, inequalities, matrix-vector equations, and arithmetic and geometric series. College Algebra is a prerequisite.
Per the current catalog, 2 tables: term 1 of the Master of Arts in Mathematics Education (Middle Grades) and term 1 of the Master of Arts in Mathematics Education (Secondary), both tracks for licensed teachers.
WGU does not publish assessment formats in the catalog. Student communities report a proctored objective assessment (OA) for the graduate trigonometry and precalculus course, consistent with the exam pattern of the matching bachelor's courses. We confirm the current format for your exact catalog year at intake, and the fixed quote covers whichever assessment the course carries.
It covers the same material, compressed. On the bachelor's mathematics education path the content is split into D667 Precalculus (MATH 1040, 4 CUs, term 3) and D889 Trigonometry (MATH 2110, 3 CUs, term 4), two courses and two terms. The graduate tracks run it as one 2-CU course in term 1. If your program plan shows D667 or D889, you owe the bachelor's versions; C647 belongs to the master's tracks.
The catalog states College Algebra is a prerequisite. On the Middle Grades track that means C912 (MATH 5015) in the same term or earlier; on the Secondary track it means transfer credit or a prior degree's algebra. We check where your algebra actually stands at intake, because a prerequisite gap turns this course from a clear into a stall.
One course starts at $99, with the exact figure fixed in writing once we know where you stand. If this course is one row on a longer remaining master's list, the master's package is $3,500 flat with the written 6-month finish guarantee covering every academic course on the plan.
