Given this equation:

e = abs(sqrt((a - x)

^{2}+ (b - y)

^{2}) - sqrt((c - x)

^{2}+ (d - y)

^{2}))

How can I solve for y if all other variables are known.

Hope that makes it clearer. I assumed a trigonometric solution was the way to go.

Two Cartesian points a,b and c,d.

Given this equation:

e = abs(sqrt((a - x)^{2} + (b - y)^{2}) - sqrt((c - x)^{2} + (d - y)^{2}))

How can I solve for y if all other variables are known.

Sorry, ignore the bit about oblique.

Basically I really want a formula that I can use to plot the location of the peak (i.e. corner at the top of the height line), given a fixed base, a constant difference between the lengths of the other two sides, and with the height known but varying.

Thanks

A slightly odd problem that I can't seem to think my way through.

I have a non-oblique triangle.

I know the base and the height, and I know the difference between the lengths of the other two sides. How would I calculate the lengths of those two sides?

Thanks!
