Content update: TX-TEKS Precalculus is now available on Khan Academy!

We’re excited to introduce our comprehensive new Precalculus course aligned to the Texas Essential Knowledge and Skills (TEKS). Whether you’re a student gearing up for advanced math or a teacher looking to deepen conceptual understanding, this course makes Precalculus clear, interactive, and accessible. 

For students and families: Master Precalculus with confidence

Take the stress out of Precalculus
This new course covers everything you need to succeed in Precalculus, from polynomial inequalities and parametric equations to polar graphs and trigonometric identities. Each topic is broken into manageable steps with guided exercises that build understanding and reduce overwhelm.

Learn by seeing and doing
Visuals and interactive graphs bring challenging topics to life. You’ll explore how polar coordinates plot points, how parametric equations describe motion, and how polynomial transformations affect graphs. Seeing how equations behave will help you build a lasting understanding.

A strong foundation for the future
By mastering concepts like recursive sequences, rational functions, and logarithmic equations, you’ll be ready for college-level math and beyond. This course helps prepare you not only for standardized tests but also for success in advanced science and engineering coursework and real-world problem solving.

For teachers: A complete and TEKS-aligned resource

Built from the ground up for Texas standards
Every unit is designed to match TEKS requirements, making it easier to align instruction to your scope and sequence. The course covers the full range of Precalculus topics, including conic sections, trigonometric identities, parametric equations, and more.

Brand-new, focused exercises
The course features a robust set of practice problems with built-in feedback that helps students learn from mistakes and reinforce key concepts. Topics like rational root theorem, recursive sequences, polar and parametric conversions, and oblique asymptotes are covered in depth with targeted support.

From skills to deep understanding
This is not just test prep, it’s preparation for mathematical thinking. Students are encouraged to explore, apply, and explain, gaining confidence as they solve complex problems and make connections between ideas. With visuals, guided practice, and a strong emphasis on application, this course supports learners at every level.
