Homework Statement Draw the axial force, shear force and bending moment diagrams. Show the locations and magnitude of the maximum and minimum values. Homework Equations See diagram. The Attempt at a Solution I've worked out the values from points A-B and then from points B-D. I...

Homework Statement Find all complex solutions to: conjugateof(z) = 2*z + (1 - i) Homework Equations The Attempt at a Solution conjugateof(z) = 2*z + (1 - i) I make: z = (a + bi) and conjugateof(z) = (a - bi) which gives: (a - bi) = 2*(a + bi) + (1 - i) then to find...

I see, so the answer should be that 1/4>= x, but because I defined x<0, I move my answer further along the number line until it meets that set criteria. That's easier to understand! Thanks for helping me out HallsofIvy. Cheers Mick

Thanks everyone for your help, I think I've got it now. I've gotten that 1/4 <= x by assuming that x>0 I can bring it across and x<0 when x is negative. I had a hard time trying to work out why I couldn't get the answer x=0 mathematically. My understanding of the question now though...

You're right, the inequality should be around the other way. I plotted the graph but now I'm even more confused? What part of the equation is swapping the inequality sign? I didn't multiply or divide by a negative as I left the variable on the same side? Am I just suppose to do this question...

Homework Statement 1/x <= 4 Homework Equations The Attempt at a Solution I initially converted 1/x back to x^-1 which gave me the answer x <= 1/4 which makes sense, but I should also get x < 0 which I'm not sure about how to get via solving? Also is converting 1/x to x^-1 the...

Thanks for your help Mark, that made it totally obvious. Much appreciated.

Question: (t-1)^4+5=3 I know the answer to the question states that there are no solution, but I would like to understand the intuition behind this. If I had this in a test I would waste ages trying to work out why I couldn't solve it. Any advice would be heaps appreciated. Thanks...
