Nonlinear Systems — Digital SAT SAT Math revision notes
A 3-page visual revision sheet for Nonlinear Systems, written for Digital SAT SAT Math. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Nonlinear Systems sheet covers
- What a nonlinear system is asking
- The setup, every single time
- the curve, in the shape the question hands you
- the line
- set the two expressions for y equal, then collect on one side
- the discriminant of THAT collected quadratic decides how many solutions
- Worked: substitution start to finish
- Graph it before you solve it
- How many solutions does the system have
- The same count, drawn twice
- Worked: a letter in the coefficients
- The three shapes this topic comes in
- Find the solution
- Count the solutions
- Find the constant
- Read the graph
- Pacing, the calculator and the typed answers
- Symbols and terms
- Traps that cost points
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans SAT Math chapter by chapter against your real exam dates and free hours, and when the plan reaches Nonlinear Systems the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
