全身痛い....

Hello,Kyoudai Fan here!

 Today I have general pain,so I wasn't able to concentrate too much.In addition,last night I didn't sleep well,so I'm still tired.What's going on to me!?

 Next week I'll have 期末試験.I hope that I could take good points,but I hardly studied this month,so I'm a little worried.

 Because of that,I'll start to sleep at 10:30,so maybe I can write the diary earlier than usual.

 Hey, does anyone know anything about trigonometric functions? Actually, I don't really understand the formula that contains the radian method in sine cosine and tangent. If you have any, please feel free to comment in the comments section.

 Ok,that's all for today,I'll prepare to sleep💤

See you tomorrow!
