  1. ME 142Engineering Computation I Excel Functions

  2. Basic Math Operations • Basic Math Operators + Addition - Subtraction / Division * Multiplication ^ Exponent ( ) Parenthesis, as need, follows algebraic precedence

  3. Finding Functions • Formula Ribbon

  4. Finding Functions • Insert Function button

  5. Sum and AutoSum • Sum • =SUM(range) • AutoSum • Note auto-selection of row/column

  6. Selecting Ranges • Use mouse to drag from top to bottom, or side to side • Select rectangular area by dragging to diagonal corners or using [shift] key • Select disconnected columns/rows by using [ctrl] key • Select a long row/column by using [ctrl][shift][end] key sequence

  7. Basic Math Functions • SQRT(x)-returns the square root of a number • ABS(x)-returns the absolute value of a number • MAX(range)- returns the largest number in a set of values • MIN(range)-returns the smallest number in a set of values • COUNT(range)-counts the number of cells in a range that contain numbers • COUNTA(range)-counts the number of cells in a range that are not empty • STDEV(range)-estimates the standard deviation based on a sample

  8. Trigonometry Functions • Excel uses Radians by default in all trig functions • Use RADIANS and DEGREES functions to convert • RADIANS(x)-converts degrees to radians where x is given in degrees • DEGREES(x)-converts radians to degrees where x is given in radians

  9. Trigonometry Functions • SIN(x) - returns the sine of an angle where x is in given in radians • COS(x) - returns the cosine of an angle where x is given in radians • TAN(x) - returns the tangent of an angle where x is given in radians • ASIN(x) - returns the arcsine of a number in radians, in the range –pi/2 to pi/2 • ACOS(x) - returns the arccosine of a number in radians, in the range 0 to pi • ATAN(x) -returns the arctangent of a number in radians, in the range –pi/2 to pi/2

  10. Logical Operators • IF(logical test, value if true, value if false) -checks if a condition is met, returns one value if True, another value if False • AND(logical1,logical2,…) -returns True if all arguments are true, otherwise returns False • OR(logical1,logical2,…) -returns True if any argument is true, returns False only if all arguments are False • NOT(logical) -returns True if argument is False, returns False if argument is True

  11. Logical Operators

  12. Time & Date Functions • TODAY() -returns the current date • NOW() -returns the current date and time • Format of the date/time can be modified
