A wave traveling in the +x direction has an amplitude of 0.45 m, a speed of 6.1 m/s, and a frequency of 16 Hz. Write the equation of the wave in the form given by either Equation 16.3 or 16.4. (Answer in terms of t and x. Assume standard units.)

You have not provided the Equation forms mentioned.

This question requires that you enter your response in symbolic format.

To do this, type your answer into the answer box using standard calculator notation.

You will be given credit for any formula that is evaluated to be equivalent to the answer formula.

For example, 4x+12 would be equivalent to 4(x+3).

Use pi to represent the symbol , 3.14 is a numerical approximation of the symbol and these are not equivalent.

Case must match exactly, however type style and character formatting can be ignored. For example, if a lowercase italic variable g is used in the question, just type lowercase g.

Example

--------------------------------------------------------------------------------

+ for addition x+1

- for subtraction or the negative sign x-1, or -x

* or nothing for multiplication 4*x or 4x

/ for division x/4

** or ^ for exponential x**3 or x^3

( ) where necessary to group terms 4/(x+1), or 3(x+1)

abs() to take the absolute value of a variable or expression. abs(-5) = 5
