@7:59, NO, the matrix is irreducible, If the number of classes is 1, then we have an irreducible, otherwise it is not irreducible.
So Good
Thank you
Lovely,though I need time to understand the concepts brought forward
definately
This was very helpful
you are welcome
Why not you give 180 degree for B component ?i ca 13:03 n 180_60teacher please?
Hi, yes, the angles are always measured from the positive x-axis.. clockwise direction means negative angle, and anti clockwise entails positive angle
Thank you Sir very much for these good explanation
You are welcome.
This is so good! Thanks 🙏
Thank you very much..
What about phycs 131
You can send in a tutorial then i will see how i can help
Thanks 😊
you are welcome..
Am not clear on drawing 72.4m , 32.0° on the Cartesian plain. Please attend to my question fast 😔
Hello, so these are estimations and so you should know that in the first quadrant your angles are between 0 and 90° and halfway of the first quadrant is 45°, so for 32 ° you're just estimating so you can draw it a bit below the 45° Mark to estimate
What can you do if you want your angle to be positive on the final answer (direction)
You consider each quadrant, the easiest way is to reflect/extend the angle in the opposite quadrant, then take counting from the positive x axis anticlockwise 🔄 to the line measured in most cases that will be the positive of the negative angle..
When you are solving you must also review questions so that we are clear.but thanks 🙏 you are very much moderate
Well noted, thank you very much
Hello
Things made easy...thanks alot❤❤❤❤
Most welcome 🙏
🦾
it has entered sir
Awesome ...
Hope we all understand the writing error @2:07 , it is suppose to be 28 and not 20 degrees
It's 28
yes yes, it was a writing error, it is suppose to be 28
About the direction isn't supposed to be 128.8 degrees since the x component is negative and the y component is positive and these are found in the second quadrant so we subtract -51.12 from 180 degrees?
really enjoyed this tutor
Glad you liked it!
Thank you so much sir🙏💕
You are Most welcome
Is number 1 interesting question sir?
Hi, sorry i missed that...what did you say,,,,
❤❤
It is okay to locate that - 51.15 south of west
hi, can you please rephrase your question..
Why can't you locate (-55.15 degrees) south of west
Sir! I believe you made a mistake! Sin(5θ) would be equal to the imaginary part of the expansion! As we said at the start (cos(θ)+isin(θ))^n=cos(nθ)+isine(nθ) and when we expand the real and imaginary parts we can say cos(nθ)+isin(nθ)= the expansion so the sin(nθ) must be the imaginary part of the expansion!!! the answer you found would be the expansion for cos(5θ), if i am not mistaken
Thank you very much, yes idea is to equate the real parts and the imaginary parts, but the question asked to show that the sin(5θ) was equal to our expansion, so we start with an initial condition which we know could have been either (cos(5θ)+isin(5θ))^n or (sin(5θ) +i cos(5θ))^n), but we just started with (cos(5θ)+isin(5θ)) since its what we are familiar with, but the actual expansion could have also been (sin(5θ) +i cos(5θ))^n), and which was the case in this question and thats why we got that, in other words it tells us that sin(5θ) was from the real part of the expansion and no the imaginary part. does that make since?..
@@aubreyundi substitute some values ion, the initial statement isnt true sin(5theta) does not equal what we have on the right hand side, it equals the imaginary part
shit explanation mate
what a legendary video, this deserves 10000000 views not 167!
Thank you @alirezaazimi5992
Good evening? Why did you interchange X/ y to y/ X when you were calculating the direction?
i didn't interchange, direction = tan^(-1) (y/x), can you say the time stamp on the video where your question is coming from.
Mr phiri its Kevin me I haven't got anything

Kindly finish answering the the tutorials 🙏
I unfortunately lost the particular tutorial sheet, but I will do something when I find it..
You could have finished the all tutorial sheet
Thank you for the feedback.. will do aswise..
Well explained😊 but you forgot to indicate square brackets on the dimensions of the formulas.
thank you very much, but sometime they can be ignored because they only help in clarifying the units

@ 4:15 It should be (u, v) = (1,3) + (2,2) +........
