I just want to know if there are ever any circuits where I am required to use voltage division, or current division, source transformation, etc will i ever be required to use them, or can i get by using node voltage and mesh current analysis? i'm asking because i have a midterm coming up...

Thanks again. Wish there was a kudos button :)

Ah, thanks. That makes a lot of sense. So h, c and e are sources, and the rest are resistors?

Homework Statement In the circuit as shown in Figure 4, there are three independent sources and five ordinary resistors. (a) Determine which of the circuit elements are sources and which are resistors? (b) Determine the value of the resistance for each of the resistors...

ok, thanks

i don;t have a specific homework question. i have a sort of conceptual question instead when integrating by substitution, how do i know what to choose as u? for example integral of z^2 / (1 + z^3)^(1/3) dz i am suppposed to choose u as 1+z^3. any other value for u won't give me the...

does that mean that what he posted above was integration? i didn't get that because we haven't covered that in calc yet. i'll go over it again and try to get it

i don't get it still ;;

o i see thanks that makes sense

Homework Statement convert 0.e to binary Homework Equations The Attempt at a Solution the method the teacher taught for numbers less than zero was multiply by the desired base. then take the whole number and write it down as part of the converted number and drop it. ie 0.8*2...

Homework Statement 1. write Newton's law in terms of s'' theta and g for a pendulum 2. define s'' in terms of theta'' Homework Equations The Attempt at a Solution 1. G = -mgsin theta and G = m s'' but i can't get all three of the required variables into one formula...

thanks. plotting sinx - x/2 is a bit hard so i plotted sinx and x/2 and found the intersection point.

i know that the answer is zero, but i might not get full marks if i don't do it algebraically

Homework Statement sinx -x/2= 0 Homework Equations The Attempt at a Solution i don't even know where to start

i'll try to wrap my head around this one. thanks btw, do you think this is a fair question for first year calc?
