2018-10-27 02:41:40 +0100 asked a question Need help with plotting

Trying to plot a line that has one point at (0,0) and the second point at (x(t),y(t)). I am trying to get it to range from t = 0 to 2*pi however, I am not sure how to do it with the line command. I am getting the following error but that is because t has no value defined (TypeError: unable to simplify to float approximation). Appreciate any help!

t = var('t')

x(t) = cos(t) + cos(2t)

y(t) = sin(t) + sin(3*t)

line([(0,0),(x(t),y(t))]

I tried using the QQ command received the following:

R.<x> = QQ[]

s = (x^2 + 2x + 1) + 1/(x^2 + 2x + 1)

print s

output-

(x^4 + 4x^3 + 6x^2 + 4x + 2)/(x^2 + 2x + 1)

Do you know why the polynomial is expanding?

Hi, I am new to sage and I am trying to construct a polynomial to try to transform it. However, when writing it I am getting an incorrect output.

x=var("x") s = (x^2+2x+1) + 1/(x^2+2x+1) s.show()

And this is the output I am getting -

x^2+2x + 1/x^2+2x+1 +1 (I am unsure why the 1 is carrying over all the way to right side)

I am looking to obtain the following output to begin transforming it -

x^2+2x+1 + 1/x^2+2x+1

Appreciate any help!

2018-09-08 12:14:14 +0100 asked a question Is there a sage command to compute complex numbers?

I trying to have sage compute the sqrt(1/z) and 1/sqrt(z) of the complex expression z = 1+ I. Is there a sage command that will execute this?
