so i made this on the graphing calc it had a diameter of 10 and i want to make a bear but i have no idea what equation to put in the y= to get something that looks like earsI have to make a picture on the graphing calc with equations and just needed advice on how to draw ears?
You could make semicircles.
A circle with center at (h,k) and radius r has the equation
(x-h)^2 + (y-k)^2 = r^2
Solve for y:
(y-k)^2 = r^2 - (x-h)^2
y-k = +/- sqrt (r^2 - (x-h)^2 )
y = +/- sqrt (r^2 - (x-h)^2 ) + k
The + gives the top half of the circle and the - the bottom half.
So let's say you want your ears to be the top halfs of circles centered at (1,1) and (-1,1), each with a radius of 1. You'd plug in :
y = sqrt (1 - (x-1)^2) + 1
y = sqrt (1 - (x+1)^2) + 1
