It would be very helpful if you would write the lowercase letter “i” that doesn’t look like the letter “s”.

@michaelhutson6758 2 года назад

Seriously! Before I played the video I thought it was S to the power of .40 plus S to the power of .50

@billharm6006 2 года назад

Total agreement. It looked like an "S" with "fly spec" notation indicating a first derivative. As soon as you said it was an "i" in the intro, the problem was quick to solve. Perhaps in a past life you hand-crafted "illuminated" manuscripts?

OMG, I'm not even searching out these clips. But this must be the most well-intentioned, yet fascinatingly terrible math instructor on youtube.

@pysankar 5 месяцев назад

I thought the exact same thing.

@pysankar 5 месяцев назад

@@keninnewmexico8763 I've learned a lot from his videos but there's way too much yappity-yap. Just get to the problem already.

@geraldaird9390 2 года назад

The best way to look at this problem is with the knowledge that raising i to successive powers repeats after 4 raisings' i^1=i i^2=-1 i^3=-i i^4=1 so divide the power by 4 and use the remainder to determine (noting that remainder 0 is equivalent to a power of 4). After all this should be thought of as a problem in Complex numbers.

@thorinpalladino2826 2 года назад

Yes, this. This will allow you to solve both even and odd powers of i. The method shown only works for even powers.

Looked to see what S^.40 + S^.50 is all about.

Thank you - I'm not the only one!

@LarrysLandFin 2 года назад

Wow, this was quite mind-blowing! 🤩

@robertakerman3570 2 года назад

Makes sense, however; U neglected to remark on what IS: "? X ? = -16"

@robertbatista50 2 года назад

Lol, i thought this was some new math I never saw. An S with a dot over it.

@danmimis4576 2 года назад

The problem is really easy but I had to start the vid to find out what that S with the dot on top is ...

@lifecycles6368 2 года назад

Didn't realise you were doing complex numbers because the i looked like an s. I prefer j to represent complex numbers!

@panlomito 6 месяцев назад

i ^( 2 . 20 ) + i ^( 2 . 25 ).... so 20 is even returning +1 and 25 is odd returning -1 so the answer will be zero.

@evangilistbarnes 2 года назад

Hey John I need to take the 5169 praxis for certification and help or suggestions for me that will help me pass?

@nicogehren6566 2 года назад

I've never seen this notation to complex numbers. good video!

@HoaNguyen-ft9hw 2 года назад

@lilpapi4399 2 года назад

Why do you write i like an s?

@tomtke7351 Год назад

are the numbers .40 and .50.? If so, and for clarity, they should be 0.40 and 0.50 oh wait.... is it i^40 & i^50? YIKES!!

@TheAZZA0990 12 часов назад

I think you are wrong!!! i squared = -1 ( NOT +1) So this problem has solution of -2 !!

@bobwineland9936 9 месяцев назад

I think it's 1+ i but lets see.

@fredsalter1915 9 месяцев назад

Please draw the "i" better so that it looks like an "i". At first, it looked like an "s".

@rexjuggler19 2 года назад

Skip about 5 minutes in past the long intro to get to the actual content and save yourself some time.

@ChavoMysterio 2 года назад

@StevenMRSenior 2 года назад

Terrible. Such an easy problem made to look so hard. Almost 5 mins bigging yourself up before even starting the problem. Anyone who has not heard of complex numbers won’t understand what you were trying to say.
