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....
Example 1:If the radius of a circular pool is 20 units, what is the length of the diameter of the pool? Solution: Given: Radius = 20 units ⇒ Diameter of pool (circle) = 2 × r. Therefore, the length of the diameter of the circular pool = 2 × 20 = 40 units. ...
iOS Unit Testing is the process of testing individual components (or units) of an iOS application, typically at the level of individual classes, methods, or functions. The goal is to ensure that each part of the code works as expected in isolation. ...
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, n...
The radius of a circle equation on thecartesian planewith center (h, k) is given as (x − h)2+ (y − k)2= r2. This is known as the equation of a circle when the radius is known. Here, (x, y) are the points on the circumference of the circle that is at a distance ‘...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
A circumcenter calculator is an online tool or application that calculates the circumcenter of a triangle based on its coordinates or side lengths. The circumcenter is the point where theperpendicularbisectors of the sides of a triangle intersect. It is also the center of the circle that passes ...
Note that the change in an object's position is not always equal to the distance it's traveled. That might sound counterintuitive, but bear with us. Run one lap in a perfect 8-foot (2.4-meter) circle and you will have covered a distance of 8 feet. However, you will also have circl...
where {eq}D {/eq} is the diameter of the circle The diameter of a circle is double in magnitude as compared to the radius of the circle. Answer and Explanation:1 Given that a circle is inscribed in a square with an area ...
Define sine with the unit circle. What is the equation of the sine function with amplitude of 8, period of 2pi, phase shift of pi/2, and a vertical shift of 10? What are the exact solutions within the interval 0,2 \pi)? sin (2x) = cos x. ...
