In case it confuses anyone else. the ellipse is much less squished when graphed on a calculator and much closer to a circle.

Thanks for sending Excel sheet (checklist)

Why did we name a for the third side of triangle?

[@karrha1]

Yea Don't know why small triangle a = 7

[@hoopersart]

@@karrha1 I suppose by definition that distance is "a" due to it being the distance to the foci point. The ellipse is centered around the origin point 0,0; and by definition of an ellipse adding distance from any point to the two foci points is "d1 + d2 = 2a" where d1 is distance from the point to one foci and d2 is the distance from the point to the other foci. In this case d1 and d2 would be equal distances so d1 and d2 would both be equal and that would mean that d1 = a; and d2 = a. so since d1 is that hypotenuse to the triangle it would be equal to a then is my way of looking at it.

Thank you for providing assistance in the Fundamentals of Engineering Exam.
Can you solve questions in mechanical engineering such as thermo dynamic and heat transfer mechanical vibrations and mechanical design

[@yajnajathan1]

Why not directly use the formula given in the F.E handbook for h=k=0 ?.
I got the same answer as yours using it.

[@directhubfeexam]

That works too!

[@sekhar4876]

Awesome!

[@natnaelberhanu-i8w]

Isn't c usually denoted as your hypotenuse?
