Google 計算機

  1. 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. 2. BASIC ARITHMETIC
  3. 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. 4. The following table lists some of the functions built into Google's calculator.
  5. 5. OPERATOR FUNCTION sin, cos, tan, trig functions (arguments are assumed to be in radians)
  6. 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. 7. Parentheses can be used whenever they'll serve to make complicated expressions unambiguous, and also sets of pare
  8. 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. 9. Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3
  10. 10. Google's calculator automatically balances unclosed parentheses.
  11. 11. A missing operator within an expression may default to an *, e.g., 6cos(2pi).
  12. 12. Feel free to experiment with the calculator as not all of its capabilities are listed here.
  13. 13. UNITS OF MEASURE AND CONVERSIONS
  14. 14. Compute expressions involving different units. By default, units are converted to and results expressed in meter-kilo
  15. 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. 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. 17. The following table lists just a few of the many commonly used physical constants known to the calculator function
