♪ Simple harmonics that don't see Simple ♪🤐

Are you back from the new year? Let's go with the tense role.# shmThat was raised to the hardest chapter of# Late physics

A lot of multisectoral connective content, because it's a hybrid of mechanics that graphs motion into waveforms, and it's not enough! It has to use mathematical ideas, especially trigonometry on a unit circle, and it's two-axis motion at the same time....Graph and then x, v, a still look different because there is a leading phase value. The phase follows mixed and confused again...Can say only one word "numb" 😵‍💫

But honestly, in that difficulty, many schools of problems are not that difficult, more focused on shortcuts, but if they are intensive schools, they have to prepare for bitter-necked problems.

For anyone who wants to prepare for a basic problem, a simple problem, a difficult problem, or a shortcut formula, we have all the values to practice. ✌️
