& how would I find its volume.GabyWed, 01 Feb 2017 23:33:21 +0100https://ask.sagemath.org/question/36431/Solid lines in plot and grid lineshttps://ask.sagemath.org/question/9244/solid-lines-in-plot-and-grid-lines/I have a plot which sweeps over a range shown below and the plots it on a log scale on the horizontal axis (I am using 5.2 so the log scale feature is present).
1. However, rather than points, I would like to see a solid line and,
2. Some grid lines on both the horizontal and vertical axis at the tick points.
3. Is there also a way to control the range on the vertical axis?
Here is the entire formulation. The range on the y-axis I would like to see labeled is from -5 to -25. I asked a question before using the formulation below but the scale did not was off due to the wrong operator being used so I did not ask that particular question at the time:
z1=2 * pi * 650 * 10^6
p1=2 * pi * 1.9 * 10^9
p2=2 * pi * 5 * 10^9
adc=.667
deltaF=.2 * 10^9
N=(adc * p1 * p2)/z1
M(freq)=(-2 * i * pi * freq + z1)/((-2 * i * pi * freq+p1) * (-2 * i * pi * freq+p2))
g(frq)=20 * abs(log(N * M(frq),10))
pts=[(frq,g(frq).n()) for frq in srange(10^8,10^11,deltaF)]
