"The Second Question" Sin Wave Question:
"A student attaches one end of a rope to a wall at a fixed point 3 feet above the ground, as shown in the accompanying diagram, and moves the other end of the rope up and down, producing a wave described by the equation y = a sin bx + c. The range of the rope’s height above the ground is between 1 and 5 feet. The period of the wave is [4(pie symbol)]. Write the equation that represents this wave."
I got Amplitude = 4, Period = [2(pie)/b], Frequency = 2/4
...Not so sure about this one...
And for the equation: y= 4 Sin (2/4(x)+4)
...I really am unsure about this one. Someone please clarify for me? I need to get "solid" in my head what the amplitude, frequency, period, and range are...And solid, a=, b=, c=...answers.
Please help me demystify this sin wave question! Thank you.
