I have been asked to draw the graph of the function f(x)= (x+3)/(x-2) I have found where it cuts the y-axis by putting x=0 but am unsure of how to find the x value. I found the inverse of f(x)= (x+3)/(x-2) which gave me x= (y+3)/(y-2) then set y=0 which again gave me x=-3 I have checked...

Is manual drawing with pencil and paper a good quality an engineer should have at his power? I'm still an undergrad and I understand all drawing is done with CAD packages, but I still enjoy drawing free hand before I put it onto software (I guess because I'm not so good at using CAD) Or am I...

I need something that I can use to draw a few simple 2D images, that don't have to look pretty. I really mean "draw" (with the mouse) and not generate from a formula, and a minimum requirement is that the program can at least let me try to draw a smooth curve with the mouse and then smooth it...

Hi, When drawing the FBD (ex. block on incline), and when you split a force into x and y components, where do you put theta when giving the angle of let's say, the incline? Is there a trick to this? I generally know where to put it (basic trig), but for some reason I can't use trig for some...

I'm just a little confused about field lines. I have sketches of equipotentials and I'm supposed to draw the field lines on them. The one I'm looking at is a dipole with a floating electrode in the middle of the positive and neutral charge. The positive is 12V, and the floating point is 6V...
