I just started my physics degree without having done further maths at a level, this topic was skipped over extremely quickly by my lecturers, they didn’t give any practise questions outside past exams and no worked solutions. You are actually saving my degree

I cannot thank you enough for making these Further Mathematics videos. I am self-studying for the CIE exams and without your videos I don't know what to do... Thank you so much and please continue making these FM videos...

Why do we introduce another term for y ? like 2λcos(2x) + μsin(2x) ???

Sir, what if the f(x)= x sinx.... this is a combination of trigonometric and linear equation... plz help

So glad I found this. I have a revision channel to go through!

Still massively helpful after 8 years.

At 1:10 you mention clicking on "this link" but there is no link.

meisterthea

what is function on the RHS is of the form xcosx instead of (constant)cosx

mlungost

Not sure how you got to the -42/65 and 24/65. Please can you share?

liberalimperial

Sir what if we have secx or cosecx or tanx or cotx ? Or even some combination of functions

ramiz

what if both exponential and trigonometric function comes up

mamatashrestha

how do I find the particular integral (pi) for ln|x|?

goodpeoplealwaysdie

Your videos are amazing. Perfectly put together, well explained and titled perfectly. You will get me through university.

hahaha thanks for your explanation nice vid

Thank you sir, however the solution is too lengthy. Isn't there another better solution that requires less time ?
