Abstract
A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.
Claims18
A trigonometric function display clock, the clock comprising:
- axial markings aligned with an x-axis and a y-axis of a clock face;
- and
- a secondary circle having a diameter equal to a radius of the axial markings between a center of each axial marking and an end of each axial marking;
- and at least one hand configured to rotate about the central axis, wherein the secondary circle is coupled to the at least one hand,
- wherein a first point on the secondary circle is aligned at the center of each axial marking,
- wherein the secondary circle is configured to be rotatable about the first point, and
- wherein the secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.
A trigonometric function display clock, the clock comprising:
- axial openings in a clock face, wherein the axial openings are aligned with an x-axis and a y-axis of the clock face;
- a secondary circular disc having a diameter equal to a radius of each axial opening;
- and at least one hand configured to rotate about the central axis, wherein the at least one hand is disposed on the second side of the clock face, wherein the secondary circle is coupled to the at least one hand,
- wherein a first point on the secondary circular disc is aligned at a center of each axial marking,
- wherein the secondary circular disc is configured to be rotatable about the first point,
- wherein the secondary circular disc is disposed on a first side of the clock face, and
- wherein at least a portion of the secondary circular disc is visible through the axial openings from a second side of the clock face.
A method of displaying one or more trigonometric functions, the method comprising:
- providing a di splay device comprising:
- a unit circle disposed on a clock face, wherein a center of the unit circle is aligned with a central axis;
- axial markings aligned with an x-axis and a y-axis;
- a secondary circle having a diameter equal to a radius of the unit circle;
- and at least one hand configured to rotate about the central axis, wherein the at least one hand comprises an hour hand, a minute hand, and a second hand, wherein the secondary circle is coupled to the at least one hand,
- wherein a first point on the secondary circle is aligned at the center of the unit circle, and
- wherein a second point on a perimeter of the secondary circle aligns with the unit circle;
- rotating the secondary circle about the first point, wherein the secondary circle intersects with at least a portion of the axial markings as the secondary circle rotates about the first point;
- and
- determining at least one of a value of a sine function or a value of a cosine function at the second point based on the overlap between the secondary circle and the axial markings.
