homogeneous constant coefficient linear equation an y (n) +· · ·+a1 y +a0 y = 0 has the characteristic polynomial an rn +· · ·+a1 r+a0 = 0. From the roots r1 ‚ . . . ‚ rn of the polynomial we can construct the solutions y1 ‚ . . . ‚ yn ‚ such as y1 = er1 x . We can also rewrite the equation in a weird-looking but useful way‚ using the symbol d D = dx . Examples: equation: y − 5y + 6y = 0. polynomial: r2 − 5r + 6 = 0. (factored): (r − 2)(r − 3) = 0. roots: 2‚ 3 weird-looking form of equation:

Algebra has long been taught in the same way. This usually means teachers rely heavily on the textbook. Though some textbooks have changed in recent years‚ the central focus is till on paper and pencil‚ memorization of rules‚ and use of algorithms. The Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) asks mathematics teachers to seek activities that “model real-world phenomena with a variety of function” and “represent and analyze relationships using tables‚ verbal rules

ANALOG MULTIPLIERS/DIVIDERS An analog multiplier/divider is a device that produces an output voltage or current that is proportional to the product of two or more independent input voltages or currents. In addition to multiplying and dividing‚ multipliers can perform squaring‚ square-rooting and modulation functions. Applications include radar‚ communications‚ and industrial controls where a real-time response is required. Analog Devices’ offers the widest selection of multipliers
