Once you ferret out the circle's center point coordinates, you can then determine the circle's radius, r. In the equation, you may not see r2r2, but a number, the square root of which is the actual radius. With luck, the squared r value will be a whole number, but you can still...
Next, complete the square of each expression in parentheses. Remember that any number added on the left side of the equation must be added on the right.(x+2)^2+(y-3)^2=1 Factor.This equation is the standard form of the equation of a circle with radius 1 and center (-2,3). To...

To graph 1 - cos(x), we need to be familiar with two things. The first is that we need to know what the graph of y = cos(x) looks like. Graph of cos(x) We see that the graph of y = cos(x) looks like a series of hills and valleys, with maximum values of 1 and mini...
The equation for graphing a sine wave that acts like a point on a unit circle is y = sin(x). How does the equation y = sin(x) relate to a point on a unit circle? The equation y = sin(x) represents the y-coordinate of a point on a unit circle, where the x-...
