1. ### Rearranging equation to find back gate bias

Thanks! That did it ...for some reason, I was multiplying 1.05 by the bracket, and going from there ...which was just making things complicated. Again, thanks!! Seán
2. ### Rearranging equation to find back gate bias

Hello, I am having a bit of an issues rearranging an equation for my solid state electronics class. I seem to have a mental block with this sort of stuff, so I am hoping someone can help. The equation is 0.34 = 1.05((0.64 + |VBS|)1/2 - (0.64)1/2) I know the usual stuff, like + to a -...
3. ### Multiplying and subtracting coordinates

Oh, sorry ....I just figured it out! Taking a break and coming back to it does help. ....just a thought, should I explain how it is done in case anyone else is looking to know this sort of thing? I don't know what the protocol would be on that. Slán -S
4. ### Multiplying and subtracting coordinates

Hello, I am hoping someone can help me understand a problem in a text book. It just assumes you know how to do a littel bit of maths, which I don't, and haven't been able to figure out. S11 = 0.894 \angle -60.6 S21 = 3.122 \angle 123.6 S12 = 0.020 \angle 62.4 S22 = 0.781 \angle -27.6...
