Chapter 5: Advanced Calculations - Advanced Keyboard s Enters a sine function to be used in a trigonometric expression. c Enters a cosine function to be used in a trigonometric expression. t Enters a tangent function to be used in a trigonometric expression. l Enters a common logarithm function. I Enters a natural logarithm function. Example • Calculate In e4. I @ @ 4 E. y Raises the preceding value to the 2nd power. If no preceding value exists, then the base value will be left blank. d Enters a mixed number, with all elements left blank. If a preceding number exists, then the number is assumed as the integer part of the mixed number. (See page 37.) b Enters a fraction. Sets the preceding value as its numerator while the denominator left blank. (See page 38.) If no preceding value exists, then both the numerator and the denominator will be left blank. a Raises the preceding value to a power. The exponent value can subsequently be entered. If no preceding value exists, then both the base and the exponent area will be left blank. (See page 38.) 68
