To find the sin/cos at a given point on the unit circle, draw a radius to that point. Then break the radius into components - one completely horizontal and one completely vertical. The sine is the vertical component, the cosine is the horizontal component.
A Tangent is a straight line, outside the circle, that just touches the circle circumference in one place. A Chord is a straight line , inside the circle, but not passing throught the centre. and touches the circle circumference in two place.
Triangle buttons and circle buttons can serve similar functions in user interfaces, but their effectiveness often depends on design context and user familiarity. While both shapes can trigger actions, triangle buttons may suggest directional movement or specific functions, whereas circle buttons typically indicate selection or activation. Ultimately, user experience can vary based on visual cues and the conventions established within a particular application or platform.
YES! If you can't do algebra, you won't last ten seconds in trigonometry. It basically is algebra, just using equations within equations.
When Cyclone Tracy hit Darwin on Christmas Day 1974, 255mm of rain was dumped on the city within a twelve hour period.
GGTTH stands for "Good Game, Thanks for the Help." It is often used in online gaming and social media to express appreciation to teammates or opponents after a match or interaction. The phrase reflects sportsmanship and gratitude within the gaming community.
A quarter of a circle or a quadrant!
Circles that lie completely within the fourth quadrant of the Cartesian plane have their centers in the fourth quadrant and have a radius smaller than the distance from the center to the x-axis and y-axis. In other words, the circle's center coordinates (x, y) must both be positive, and the radius r must be less than both x and y. This ensures that the entire circle falls within the boundaries of the fourth quadrant.

Then it could be a straight line segment within a quadrant
cos(495) = cos(495-360) = cos(135) = -cos(180-135) = -cos(45) = -sqrt(1/2) or -1/sqrt(2)
It is an acute angle
An angle in a quadrant refers to an angle formed by a ray that originates from the origin of a coordinate plane and lies within one of the four quadrants. Each quadrant is defined by the x-axis and y-axis, and angles in a quadrant are measured in a counterclockwise direction from the positive x-axis. The measure of an angle in a quadrant typically ranges from 0 degrees to 90 degrees.
It is the complement to the sine, and the opposite relationship within a triangle in regards to the Pythagorean Theorem.
The points in a circle are just points in a circle. Also, a plane cannot be within a circle because planes go on forever in all directions, so a circle can be within a plane.
