Awater wave is created in a wave tank. it has an amplitude of 3 and a period of 4pi/5. find the equation of this wave as a sine function.

Step-by-step explanation:

1. You know the following equation of sine function:

2. Where:

A is the amplitude.

C is phase shift and D is vertifcal shift

3. C and D are zero. Then:

4. Substitute these values into the equation:

d

step-by-step explanation:

i used the pitagoras theoreme

d
