This lesson focuses on defining a circle, presenting its equation in two different forms (standard and general), and giving examples of how to solve problems. Related to this Question 1. What is the equation of the circle with center (-4,-3) that passes through the ...
For a unit circle, this distance is 1 unit, or the radius is 1 unit. Let us learn the equation of the unit circle, and understand the ways to represent each of the points on the circumference of the unit circle, with the help of T-ratios....
A line is a straight edge that has no start or end point. In geometry, we can express the equation of a line in two-dimensional plane using the intercepts formed by the line on the cartesian axis as shown below.Answer and Explanation: ...
The standard form equation for the unit circle is: x2+y2=1 Intersection with a line: To find the intersection of a line with the unit circle we substitute the equation of the line on the equation of the unit circle and solve the quadratic equation....

, the equation is: First, we draw two circles, one for and the other for , plotting their elements in an anti-clockwise direction: To calculate , we substitute into our circular convolution equation: The sequence is the circular folding of ...
The Earth’s orbit is slightly elliptical—it’s a not-quite-perfect circle. When the Earth iscloser to the Sun, it travels more quickly along its orbit. The Earth’s spin axis is tilted—around the solstices, one of the Earth’s poles isleaning toward the Sun. Around theequinoxes, ...
