Tangent to a circle is line that touches circle at one point. At the point of Tangency, Tangent to a circle is always perpendicular to the radius.
A circular function coordinate can be found using the formula (r cos(x),r sin(x)). Here r is the radius of the circle and x is the angle.What are Circular Functions? The trigonometric, or trig, functions, such as sine, cosine, and tangent, are also called circular functions. They ...
To define the trigonometric functions, we may consider a circle of unit radius with two mutually perpedicular diameters A’A and B’B (Figure 1). Arcs of arbitrary length are plotted from point A along the perimeter. If the arcs are laid out in the direction from A to B, that is, ...
To find the area of the shaded region, subtract the area of the small circles from the area of the large circle. Each small circle has a diameter of 2, so each has a radius of 1. Plug this value into the formula for the area of a circle:A_((small circle))=π r^2=π(1^2)...

Tangent Line to Circle: The tangent line of a circle is obtained when we know the value of the slope and coordinates of the point(x0,y0)so that we can substitute these values in the general formula of the tangent liney−y0=m(x−x0). For the slope, we'...
