  • 1. Google 計算機 Quick Reference: Google Calculator (Cheat Sheet) GOOGLE GUIDE by Nancy Blachman – nancy at googleguide.com (replace at with @) Solve mathematical problems with Google's built-in calculator function. Simply enter the expression you'd like eval
  • 2. BASIC ARITHMETIC
  • 3. OPERATOR MEANING + or plus addition – or minus subtraction * or times multiplication / or divided by division % of or percent of percentage of mod or % modulo (the remainder after division) ^ or ** raise to a power the nth root of nth root reciprocal of multiplicative inverse ADVANCED MATH
  • 4. The following table lists some of the functions built into Google's calculator.
  • 5. OPERATOR FUNCTION sin, cos, tan, trig functions (arguments are assumed to be in radians)
  • 6. sec, csc, cot arcsin, arccos, arctan, arccsc, etc. inverse trigonometric functions sinh, cosh, tanh, csch, arsinh, arccsch, hyperbolic functions etc. ln logarithm base e log logarithm base 10 lg logarithm base 2 exp exponential function ! factorial x choose y calculates the number of ways of choosing a set of y elements fr choose elements CONSTANT MEANING e base of the natural system of logarithms pi the ratio of the circumference to the diameter of a circle i imaginary number, which represents one of the two square roots of -1 gamma Euler's constant TIPS (adapted from Google's Online Calculator Help)
  • 7. Parentheses can be used whenever they'll serve to make complicated expressions unambiguous, and also sets of pare
  • 8. You can force the calculator to try to evaluate an expression by putting an equals sign (=) after it. This works only if dividing a non-zero number by zero is undefined and not computable).
  • 9. Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3
  • 10. Google's calculator automatically balances unclosed parentheses.
  • 11. A missing operator within an expression may default to an *, e.g., 6cos(2pi).
  • 12. Feel free to experiment with the calculator as not all of its capabilities are listed here.
  • 13. UNITS OF MEASURE AND CONVERSIONS
  • 14. Compute expressions involving different units. By default, units are converted to and results expressed in meter-kilo
  • 15. TYPE OF UNITS UNIT CONVERSION old units in new units Currency (money) 23 USD in Euros Mass 130 lbs in kg Length 3 miles in km Volume three quarters of a cup in teaspoons Area 2 acres in sq km Temperature 98.6 Fahrenheit in Celsius or 98.6 f in c Time 1 year in seconds Electricity 100 volts in picovolts
  • 16. Energy 160 lbs * 4000 ft in Calories Power 1 hp in watts, 500 V * 3 A in KW 90 degrees in radians Angle Information 2 bytes in bits Quantity 1 great gross in dozens 1500 in hex Numbering Systems 64 in binary LVII in decimal PHYSICAL CONSTANTS
  • 17. The following table lists just a few of the many commonly used physical constants known to the calculator function
