such as the quadratic formula used to solve quadratic equations, or the relationship described by the Pythagorean theorem that relates the lengths of the perpendicular sides of a right triangle to the length of that triangle's hypotenuse,
Figure 3: Right triangle and its sides. Using the Hypotenuse Formula for Circles To apply the formula shown in the previous section to find the equation of a circle, one must follow these steps: Preferably, the circle must be drawn on a coordinate system to facilitate finding positions and ...
Here the values of x and y are the lengths of the base and the altitude of the right triangle. Now we have a right angle triangle with the sides 1, x, y. Applying this in trigonometry, we can find the values of the trigonometric ratio, as follows:...
The radius of the circle (length = 1 unit) represents the hypotenuse of the right triangle. So, the sides of the right triangle are 1, x, y.By the definition of the trigonometric ratios, we havesinθ=OppositeSideHypotenuse=y1 ⇒y=sinθ...

to the x-axis, then we get a right triangle, where radius of the circle is the hypotenuse. the base of the triangle is the distance along x-axis and height is the distance along the y-axis. thus, by applying the pythagoras theorem here, we get: x 2 +y 2 = radius 2 equation...

This allows us to connect the geometry of a right triangle (Pythagoras theorem and the lengths of the sides of the triangle, sin x and cosx), with the geometry of a unit circle (the angle of rotation x of the radius relates to the distance traveled around the circumference in radians)....
