Algebraic operations:

• Adding & Subtracting with significant figures:
  1. Perform the calculation
  2. Determine the least # of decimal places in problem
  3. Round answer to that # of decimal places
• Multiplying & Dividing with significant figures:
  1. Perform the calculation
  2. Determine the least # of sig figures in problem
  3. Round answer to that # of sig figures
• Scientific Notation—a short hand method of writing numbers using powers of 10.
• Writing scientific notation:
  1. The decimal point is always moved to after the 1st non-zero number.
  2. Count the number of times the decimal point is moved and use this as the power of 10.
  3. “Big” numbers (>1) have positive exponents.  “Small” numbers (<1) have negative exponents.
• Trigonometry review:
  Trig functions are often used to find resultants and components.  The most useful
  relationships are:

• Quadratic formula:
  The quadratic formula is sometimes useful for squared functions:
  
  
• Graphing:
  Data is often graphed in physics.  Theses relationships are often analyzed to fit mathematical models.

Mathematics is vital to your study of physics.  Algebra is needed to isolate and solve for whatever variable is desired.  Physics often deals with very large, or very small values.  Significant figures and scientific notation make these extreme numbers manageable.  There are often many mathematical applications in physics.  Your previous knowledge of geometry, trigonometry, and graphing will all come into play with physics.  These tools will be used throughout many of the topics in this series.
