Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

spent whole day reading different pdf..but did not understand..watched this 24 minute video and everything is clear...Thanks alot for this great effort:)

Very good and clear, potentially a little slow for those that understand most of the method (for example homog eqns) but are stuck at solving with the RHS (the non homog part). 

[kristakingmath]

YES, that's the best compliment you could give me!! I'm so glad it helped!! :D

I'm still confusing about the transform if the r(x)=k.e^x
For example, r(x)=3e^x, what i've learned the yp=Ae^x

Thank you so much ; indeed it works way more when using the initial conditions on the general equation and not on the homogeneous equation only...

[sarahsal]

Thank you very much. You answered all my questions. Very clear and nice explanation and hand writing. Thanks again!

[kristakingmath]

Thank YOU so much for the comment! It makes me happy. :)

I was just looking for solving these problems with initial condition! Nice Work!

[jeshpaul]

first of all i would like to thank you very much for teaching this stuff madam.i want you to tell me the answers to these problems i got in my exam.
1. y’’- λ2y =sin2x is the differential equation .What is the solution?
2. Find the length of the arc of the curve y = │x-1│+│x-2│ from x=1 to x=3

thank you very much once again

Reallly helped…. Got a test in 4 hours👍🏼

[sahandbagheri]

SO happy you are not my professor. I can not focus, your voice is amazing :D BTW, the video is great

[westonmulenga]

nice job!
you are the best, keep it up
for me just tone of your voice makes me watch all your math videos

[matzzcoizzyboy]

very helpful, Keep helping us the student please. Your help is highly appricated.
Thanks

try a particular solution of y_p=A, instead of y_p=Axe^x. i haven't worked that out, but it's a good first guess! :)

[akigamingnetworkagn]

thank you for this video. i actually understand the concept now :)

[polywolf]

Cheers! got an exam on this tomorrow. Much easier to understand! However i prefer to leave Yp in the form of Ae^x. Didn't get confused by it and found the calculations easier. :) keep up the good stuff

[bijoy]

Thank you very much.
You have done a great job.
I love the way, you explain, everything details.

[kristakingmath]

You have to use the integrating factor method. I don't have a video on it yet, but if you type "integrating factor method for second-order differential equations" into YouTube, I'm sure you'll find one! :)

[shwethashukla]

The answer is supposed to be e^-x ( 8x^2 + 4x + 1)
if guess the particular solution to be xe^-x (Ax + B) from where does the constant term ( 1 ) shown in the answer come from?

Hope you make more videos until i finish my math major! Your a great instructor
