Essential Formulas & Mathematical Definitions
∫ u v dx = u ∫ v dx - ∫ [u' ∫ v dx] dx
King's: ∫[0 to a] f(x) dx = ∫[0 to a] f(a-x) dx
dy/dx + P y = Q
IF = e^(∫ P dx)
y · IF = ∫ [Q · IF] dx + C
First-Order Linear Differential Equations
Multiply standard form dy/dx + Py = Q by integrating factor IF = e^(∫P dx) to integrate directly.

High-Yield Exam Strategy & Scoring Tips
Step-by-Step Mark Allocation
Always state the governing principle or formula first, write given values with standard SI units, substitute clearly, and highlight the final numerical answer with units in a box for full step marking.
Common Calculation Traps
Watch for unit prefixes (cm to m, minutes to seconds, g to kg, degrees to radians). In coordinate and ray optics problems, double-check Cartesian sign conventions before computing.
