Okay. Anyway, the book uses capitalized subscripts for DC values. When you wrote "Rc", you used lower case "c" subscript. For example, the book says, Vc=Ic*RC where both "Vc" and "Ic" are AC values while "RC or R_C" a DC value.
I don't think that the book is correct. The output is inverted therefore there should be a minus sign to show that inversion for the amplification. As the voltage across transistor drops/rises, there is an equivalent rise/drop, respectively, in voltage across R_C. Hence, Vc=-(Ic*Rc).
Also, I do believe that it should have been "Vin" instead "Vs".

I thought that I should confirm this with you. From our previous discussion, it was said and concluded that both voltmeters, ckt_bjt111, would read the same, right? Thanks!

The sum of the voltages across the transistor and Rc equals Vcc. Therefore, if the voltage is large across the transistor, it is small across Rc and vice-versa. That makes the amplitude of the voltages unequal.
So, what was Vc in the link below? Is it the voltage across transistor, or the voltage across resistor? I'm sorry but I need to confirm this. I had thought that Vc is voltage across the transistor.
