Eeeeee😶🤣

Next week is the midterm break, so I have a one-week vacation and I will be at the school, but I can write from time to time. However, I am a little busy this week, so we can still message each other.

I have a chemistry exam today and I've been up since 4am 🥱

I think I solved the problem

sin 3x + sin 2x - sin x = 4sin x * ((cos x)/2)
sin 3x = 3sin x - 4sin^3
sin 2x = 2sin x * cos
3sin x - 4sin^3 x + 2sin x * cos x - sin x =
(3sin x - 4sin^3 x + 2sin x * cos x - sin x)
We can simplify the equation with sin x, but we must make sure that we do not miss the case sin x = 0. When we simplify with sin x in the case sin x ≠ 0, we get:
2 + 2cos x - 4sin^2 x = 2cos x * (cos 3x)/2

Let's expand the right side:

2cos x * (cos 3x)/2 = cos x * cos 3x

Using cosine expansion, cos 3x:

cos 3x = 4cos^3 x - 3cos x

If we substitute this expression:
2 + 2cos x - 4sin^2 x =cos x(4 cos^ 3
It may be necessary to examine these expressions in more detail later, but the important thing is to examine the equation under a corner case. In the first case, when sin x = 0, we can solve sinx = 0 ⇒ x = n.

Solution:

↓

x = ηπ, NEZ

I think this is x

I told you that such a thing would not happen. I have been using this app for years and it has always had a small and nice audience. So it WILL NOT CLOSE!🤨

Hı 😉

Yes yes yes

Dude, it's great that you know this series, I just started watching it

Yes, I usually leave home at around 8:30 in the morning and come back at around 9 in the evening. This makes me very tired and when I'm out, I just study and go from place to place. I'm also a writer and despite all this school and exams, I have a novel to finish 👍 . So, yes, I'm always a busy person 🥲

Hı 😎

Np 🤓

I listened to it, it's a nice song but you know I like a little more rap and rock like Fall Out Boy or ceza

You?

It changes sometimes I work with music sometimes without music.

Dude, my English is seriously being tested. What did I do to warrant this explanation?🥲

am I working too?
