Task 40461.
Material point participates in 2 equal frequencies and oscillation amplitudes and occurring in one direction. The period is equal to 8. The amplitudes are 6 cm fluctuations differ only the initial phases, which are:. 0 and -n / 2. Write the equation of the resulting vibrations and make a drawing with the vector representation of the oscillation.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
