You're right I'm pulling my hair out with it already, i'll get there in the end though! Just one last thing though. How would the anti derivative e^ax work? I'll be harassing my lecturers tomorrow haha.
My level of maths is not too good I have to admit. I was on an easier degree course last year which had a background in the built environment it still had some maths and physics elements but wasn't as heavy on integration and differentiation. The course transferred over to a harder engineering...
Ok I see that one of the exponents was -1.4 so adding that 0.8 will give us 0.6.
I have checked out my notes I just have a basic list of integrals and can't seem to find anything similar online for eax so would it be similar to eax+b where I would just miss out the plus b part? So it would...
This is what I had
e0.8x = ∫ e0.8x*0.6e-1.4x
So should it be this instead where the multiplying exponents just add together?
e0.8xy = ∫0.6e-2.2x
What would happen now?
Would the rhs integrated become 0.6 ln(-2.2x) ?
Homework Statement
Hi, I submitted this question on here the other day a user suggested some topics which might help so I have went away and tried this and this is what I have came up with. I just want to know what I have so far is right also I need help with integrating the rhs of the...
No, we covered Fourier series over an hour we didn't really get into it much we got a couple of pages of notes and some examples nothing like that was mentioned.
I haven't drawn it yet I have an example from my lecturer which is similar up until that point, when I have to integrate using 1.7(x+1) on the example there is no mention of odd or even numbers. I couldn't tell you if it mattered or not.
Homework Statement
I have a periodic function which has a period 2, which is defined as
f(x) = ( 1.7(x + 1) , -1 ≤ x < 0 With f(x+2) = f(x) for all x
( 1.7(x - 1), 0 < x ≤ 1

I have started this as
a0 = 1/T ∫ top limit = T/2...
Hi sorry your probably right that it should be (1.4) there is also an x on the outside of the bracket meaning it would be e^(1.4)x. I don't know what integrating factors are. This subject is a bit of a mystery to me I've gone through the class notes about half a dozen times and I just can't...
Homework Statement
dy/dx + 0.8 y = 0.6 e ^-(0.6+0.8) , y(0) = 1
Solve this ordinary differential equation subject to the given condition using exact methods and evaluate the solution y for x = 0.0 (0.05) 0.5, i.e from x = 0 to x = 0.5 in steps of 0.05).

Homework Statement
I have a problem which I will attach a picture of, regarding a system composing of a heat recovery steam generator and a turbine. I have to work out the power output of the turbine, which I think I will be fine with. What I would like to know is, how does the combustion...
Hi, I have been checking out basic spring accelerometers. What I would like to know if it is possible to use mass on the end of a spring to calculate g-force and would it be possible for someone to point me in the right direction for how I would begin to do this
Thanks
