When you're too used to √2/2

The Chinese reaction is so good 😂

I’m dying of laughter! When you said that there was no exact solution I was like “nooooo” in my mind. Moments like these happen to us all

In case anyone needs it, here is the translation to the last sentence Chinese: 等一下，有哦！我在耍白痴哦，我在耍白痴哦？ English: Wait a minute, it has (an exact solution)! Am I stupid? Am I stupid?

My mind during exam Confidence 💯💯 Accuracy🅾️

😂😂😂😂😂 I was like that's (sqrt2) / 2, so there is an exact angle, and it's pi/4 rads!

Or 45 degrees.

That moment of realization hit too close to home

My mind immediately goes to rationalize even when I don't have to

How can I get that trig identity poster ?

Link to the poster

i wanted x to be degrees instead of radians, as arcsin(1/sqrt(2)) (in degrees) is a clean number, 45. and the second one would be -45. Dang.

45 degrees is equal to π/4 radians. So even in radians, arcsin(1/√2)=π/4 (a clean number) The joke in this video is that he didn't realise arcsin(1/√2) is an exact number (π/4)

Technically radians are more accurate

Bro youre gonna make me cry😭😭😭 Context: I have been struggling with maths and my pessimistic(sorry for that) brain likes to know and watch others make mistakes(i really am sorry)

does he know that he's changing the domain when putting the inverse sine function?

Nah I don't think he thought that far ahead but yes we have to use trigonometric general equation for that so theta= npi + (-1)^n pi/4 and using inverse there is wrong.

@@SunnyRosy-uk1ch why do u need to use that when your domain is limited between 0 to 2pi? There are only 2 positive solutions for sin in the 1st quad and 2nd quad respectively, giving us pi/4 and pi-pi/4. Similarly, for negative ones we have 2 solutions only, 3rd and 4th quadrant, giving us pi+pi/4, and 2pi - pi/4

blue pen, red pen = bprp black pen, red pen also = bprp

Hopefully you took care of this when you redid it, but there are 4 solutions and only one of those arcsines is one.

Why not do it in a faster way:cos2x=0

=√2/2 so the answer is π÷4
