Hi there!

I'm having trouble with Intergalactic Op amps. I'm fairly new on the subject, I've seen lots of stuff on the internet regarding a DC Input but nothing regarding Sine waves.

I've attached the question so anyone can have a look at it, I am suppose to draw the output.

So far I've got:
Vout = -Vin/RC
When Vin = 5mv, vout -= -10mV
When Vin =-5mv. vout = 10mV

I know there is also a phase shift, I suspect it'd be either + or - 90 degrees.

I have no idea how correct this is or even if I'm on the right track. A bit of help would be great

Thanks guys, I swear by your tutorials!

 

You're on the right track. Have you ever used phasors before? They are a nice way of dealing with sinusoids instead of dealing with differential equations. You basically transform each component into its phasor form then solve the circuit like you normally would, turning a differential equation problem into an algebraic problem.
