Could I get a conceptual answer, supported by math, explaining why coax has less characteristic impedance than open wire feeds?I’m new to EE. Thanks for you patience.
The tutor wrote that out
I think the compressive strength is the inverse of the bulk modulus?
Could someone walk me through the problem solution? A few steps are skipped and the reasoning is not explicitly stated.
Hi, I'm afraid I not very good at these questions just yet and would like a walk through a bit better than the one I was given by my tutors.
Thank you, please refer to the inline image.
Oh I see so this is not some convention, but merely indicating the points on the graph?
I've just never seen an asterisk used before, they usually use a different letter value (a, b, c) to designate constants.
Can anyone confirm the previous poster?
I can obviously do the chain rule and see how the final expression of the derivative is related to the original function but I can't seem to figure out the substitution Rule as an intuitive way of solving the indefinite integral of functions... bear with me if I'm too verbose, I've attached an...
Hi,
I may have discovered a textbook error but I'm no calc whiz. I need an assist to find out if the question unintentionally described a square instead of a rectangle.
I have attached the textbooks solution as well as my attempt at a solution.
The numbers check out, I just want to make sure...
I need to find the max/min of a function on an interval.
The function is f(x)=x+cos(x) and the interval is <-PI,2pi>
There is an attached solution but I do not understand how to arrive at the given solution (see screenshot). I would personally just take the derivative as
F'(x)=1-sin(x)
However...
That is the identity I used to expand the (x+h) terms but could not factor to the next step due to the sin(h) term... unless I made an error in my expansion that I haven't caught?
