| Abstract: | In college physics teaching materials, analytical method or vector representation is usually used to solve the problem about simple harmonic vibration and simple harmonic wave. The article brings in the rotation speed vector and rotation acceleration vector of simple harmonic vibration to solve the initial phase problem of simple harmonic vibration, which can be more visual and quick than using analytical method. |

| Keywords: | rotation vector simple harmonic vibration rotation speed vector rotation acceleration vector problem solving. |
