I am in grade 10 and I only undrstood what is Integer,Natural no and odd no.😢
Hie may you kindly do a video on ANYLOGIC
Thank you Sir, I appreciate it 🙏🙏
Thank you so much Sir.
Great! It's very clear.
thankyou
Thank you Sir
how would answer a question like this "What special condition exists? Explain how you will proceed to solve the problem"?
give a qestion of another thank you''''''''''''''''''''''''''''''''
Thanks 🇮🇳
Sir where did the 2s on the numerator of the final answer come from ?
When you put that fraction under a common denominator, in the numerator you get: (s-iw)+(s+iw) which is equal to 2s
also in the event that takapihwa ma plot points and no diagram , is it a must ku drawer diagram rine ma marks here assuming i can work and still get to the answer without diagram construction
The diagram just helps you visualize the problem, it is optional to include it in your solutions.
greetings sir , so there isnt a case in wch we are given that evaluate qsn at the begining of the video with no diagram and no plotting points ryt? if there isnt a diagram then is its a must for us kuti tipihwe ma plot points so that we construct the diagram 4 ourselves
If a diagram is not given, then you have to plot it if necessary
much appreciated thank you
thank you
Sir in what situation do I use that formula in brown , can’t I just substitute y=u^-2 throughout my equation like on the previous Bernoulli equation question
You use it if you think it is convenient to do so, if not, then make substitution like the previous question.
What are my chances of passing the exam if i get into the exam ,given that ive mastered ODEs and Linear algebra only with little to close to Zero knowledge of LAPLACE n vector calculus
It’s possible to get to 60% with those 2 topics
greetings, sir so table on method of undetermined coeff wch is on finding the particular solution inana nth term and all , we are not given that as well?...the only table we get in the whole course is yema LAPLACE?
Yes, you are only given the table of Laplace Transforms
Great
Tq so much
so we are not given identity tables in the exam like they used to in A level?
Yes. The only table you are given is the table of Laplace transforms.
GREETINGS SIR , I have a question pertaining to the ODEs , how do u determine m1 and m2 for example u solved an auxiliary eqn and got -1 and -6 as the roots unoziva sei kuti m1 kana m2 ndeupi
you can have m1=-1 m2=-6, or write m1=-6, m2=-1. This does not change the solution of the ODE
Sir please do the MODI method
That was awesome
sir ,at 11:22 mins of the vid, x3 becomes alpha ,why is that isnt it we have an equation that says x5=-x3 why cudnt x3 be -x5 there im failing to see whyx3 had to be assigned alpha when the x5=-x3 equation exists ,also may u assist me on when do we assign alpha and beta ,tomuisa kana zvaita sei.thank you
When finding eigenvectors it is convenient to write all variables in terms of the lower numbered variable. In this case x1 and x2 were 0, so the lower numbered variable remaining is x3. We write all the other remaining variables in terms of this x3, that is x5=-x3. We assign to the variables real numbers alpha or beta when we want to factor common terms from the vector since there is no rule that allows us to factor a variable from a vector.
When dealing with Integrals, dont we have an upper limit and lower limit because when we calculated for C1 we fixed the upper limit as a -2
The arrow on the integral is indicating we are moving in the counterclockwise direction. Along C1, when moving in that direction, x varies from 2 to -2. So we integrate from 2 to -2.
Good at explaining
Lovely
Euler's formula is it provided in the examination or i should memorize it
It’s not provided, it’s a formula you should recall.
wow..
sir, why die square the denominator at 3:17
We found the norm of the vector -j. When finding the norm, we square the components of the vector and take the square root. So we had the square root of (-1)^2
C is the boundary of the region R in the first quadrant bounded by the graphs of y=x, x=0, and x=1.
sir please do upload more content because this topic is interesting
what happens when we interchange m1 and m2 in the complementary solution?
The solution remains the same since the constants c1 and c2 are arbitrary. interchanging m1 and m2 does not alter the solution, it just alters its presentation.
thank u sm
we are here broo
Thank you sir.... from Egypt
You are heaven sent🥹🙏I’ll now be able to write an exam
sir ma vid aya mangani akungo wedzera daily...will all this content come on thursdays test.
I’m just trying to answer the questions on worksheet 2, yes all content will be examined
Sum of eigenvalues = trace of the matrix?
Yes, if the matrix is triangular.
We are failing to write cos(x)cos(y)
Did you include the multiplication sign?
Yes we did. @HarareMaths
@MudereriTawana-lp2gd send a screenshot to my email
Sir may we please have a video on how to diagonalise matrices and normalise vectors using matlab
MATLAB | Vectors ua-cam.com/video/QXct_7IEFyc/v-deo.html. Check this video. For normalizing, you divide the vector by its norm. In the video I indicated you, can see how you find the norm of a vector.
We are having trouble with getting the eigenvalues values....... we are getting them in expressions
Can you send a screenshot to my email?
vectors
Is the order of the eigenvectors in the matrix P important ,for example if you started with with (1,0,0) vector first instead of (4,-10,_5). Would that have made a difference
It’s not very important. But if you start with the vector (1, 0, 0), then your diagonal matrix will start with the eigenvalue corresponding to this particular vector.
So well explained, awesome video. Thank youuu
this was so helpful
