Which Trigonometric Function Is An Odd Function And Why

Question: Much of the electricity generated for home use

Answer: alternating current

modeled using the sine curve

Question: The transformer

Answer: can change the voltage of the electrical current using phase angles

has three coils at 120° angles to each other

coils;

• produce three waves that have the same magnitude

• - out of phase with each other by 120°

• Question: amplitude

• Answer: the maximum displacement from the horizontal line of symmetry for the sine and cosine functions

• Question: even function

• Answer: A function that satisfies the property f(-x) = f(x)

• Question: odd function

• Answer: A function that satisfies the property f(-x) = -f(x)
