elipse

[kopend]

i need a to scale drawing of an elipse
158 long x 112 high
not sure if thats how you word it??

but i looks complicated when i looked up how to draw it
i think its easy with CAD but i dont have it

Do you need to know how to do this free hand?

If not, just draw a circle in MS Paint, then choose stretch/skew and enter 158 and 112 in the stretch boxes.

Well the equation of the ellipse is:
x^2/a^2+y^2/b^2=1 where 2 x a=158 and 2 x b=112, so a=79 and b=56.
so if you want to draw the ellipse actual size then since
y=+ or - 56 x sqrt(79^2-x^2)/79, you can substitute a value for x starting at x=-79 and continuing to x=+79 and plot the values of y(+ and -) against each x value. You can scale it down by dividing each x and y value by some number such as a say=79 and then the values will all be <= 1.
