Essential Formulas & Mathematical Definitions
LHS Dimensions = RHS Dimensions
ΔZ/Z = (ΔA/A) + (ΔB/B)
Z = Aⁿ ⇒ ΔZ/Z = n(ΔA/A)
Error Combination Rules
Absolute errors add during addition/subtraction. Relative/percentage errors add during multiplication/division and multiply by exponents.

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.
