thanks ! sorry and for this one ∫x-3 / x^2+2x-3 .. i think can't do the same as the previous one because would be bottom 2x + 2 but in the top is x - 3 so is a bit impossible to do the previous method. but can i do by partial fractions (x+3) (x-1)

Hello I am trying to integrate this problem: ∫x-1/x^2-2x-3 My attempt solution is differ x^2 - 2x + 4 = 2x - 2 and basically the top x-1 can be manipulate by multiplying 2 this would give me the answer as 2 ln|x^2-2x+4| + c I am not sure I am right can somebody...

Hello, Im trying to understand boolean algebra, I have to do the next problem using Boolean algebra and Identities for this one: So far this what I got: A + /A (A+B) = A + B A + /AA + /AB = A+B A + A + /AB = A + B A + A + B = A + B <-- I think A + A = A so .. A + B = A + B <-- I am not sure...

Hello, Im kinda of new beginner I am looking for virtual program to get Voltage in and Voltage in a design circit using the oscilloscope and function generator, I using ISIS Design and I can get the oscilloscope getting the sine wave, and the function generator that helps to change the...

Sorry for what is the answer 0.707 ? I don't know how to do the operation

is this right? because somebody said early before that I was wrong... sin (u) = 0.707 ?

Im really confused I don't even know any relevant formula I just tried to move the x

Solve for x between 0 , and 2pi the next equation? cos x + square root(3) sinx = square root(2) sin(x+ (pi/6)) = 1/sqrt2 <-- but then I don't know what to do this what I think should do, but I am not sure how to solve x help me thanks!

SOrry I got confused but I still doing right, the value of C2 that is 1 uF it doesn't work when is connected with the potentiometer only if I take off the C2 and connect the C2 next to pin 3 would be working , but with bad quality audio. I do this circuit so it should be errors nobody provide me...

Hello people I am doing an audio amplifier, but I am really stuck in the circuit because the 1uF capacitor (C2 )doesnt work properly next the the potentiometer , but if I took off the Capacitor C2 I can hear music through my speakers, but with really bad quality. I don't know what you can...

so that means it could be 5.7 V? or more

So I am still stuck I don't know how to do this what formula can I apply? can you please explain me

is open notebook test lol is why the teacher wants to show us the work and I still not understanding what is the answer ? is not -10.8 V?

MmMMmM this is really hard for me I struggling a lot but I think is 9mV it doesn't have any resistor affecting before the Vout but I am not sure at all :/ there is no way using a formula or something like that?

ok so which formula do I have to use? cause I was looking at my teachers notes and this the only thing I find similar
