Dear sage users, I'm trying this piece of code (
http://alpha.sagenb.org/home/pub/16
)
x,y = var('x y')
(x_min, x_max, y_min,y_max)=(0,2,0,4)
f(x,y)=cos(y)
A=plot_slope_field(f(x,y),(x, x_min, x_max), (y, y_min,y_max))+text
(('$y\,^{\prime}=%s $'%latex(f(x,y))),(x_max,y_max),
vertical_alignment="bottom",fontsize=20,horizontal_alignment="right")
show(A,ymax=y_max+0.5)
The problem is that the string \cos\left(y\right) which is rendered
well in LaTeX has bad parentheses - see the picture.
The parentheses are shifted down and are too small. Do you have any
idea how to solve this problem?
Thank you
Robert
