The Mathematical Expression of an AC Sine Wave As a Function of Time: Practice Problems
Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.
Learners read definitions of the terminology associated with algebraic operations and then follow steps to use the fundamental laws of division to simplify algebraic expressions.
Learners read definitions of the terminology associated with algebraic operations and then follow steps to use the fundamental laws of multiplication to simplify algebraic expressions.
Nouns: Count and Noncount with "a Few" and "a Little": Part 4
In this interactive lesson, learners study examples of the expressions "a few" and "a little" with count and noncount nouns. They practice using these expressions in a drag-and-drop exercise of 20 sentences.
Learners read how the NOR gate can be configured to obtain the other common logic gates. Schematics and Boolean expressions demonstrate how the AND, OR, and Hex Inverter functions are achieved through the use of only NOR gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Learners examine how language can interfere with clear communication. They select examples of ambiguity, assuring expressions, doublespeak euphemisms, jargon, emotive content, false implications, meaningless comparisons, and vagueness. In an interactive exercise, learners identify ways to overcome these barriers.
