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.

Which circles lie completely within the fourth quadrant?

A circle with centre (x0, y0) and radius r has the equation of:(x -x0)&Acirc;&sup2; + (y - y0)&Acirc;&sup2; = r&Acirc;&sup2;By writing the equation of any circle in this form its centre and radius can be determined.To completely lie within a quadrant, the centre of the circle must be more than r away from the y- and x-axes:In the first quadrant if: x0 > r and y0 > rIn the second quadrant if: x0 < -r and y0 > rIn the third quadrant if: x0 < -r and y0 < -rIn the fourth quadrant if: x0 > r and y0 < -rIf either x0 or y0 (or both) is exactly r away from the y- or x-axis then the circle is on boundary between quadrants, and if either x0 or y0 (or both) is less than r away from the y- or x-axis, then the circle is in more than one boundary.f x0 < r from the y-axis then the circle is in quadrants I and II, or y0 < r from the x-axis then the circle is in quadrants III and IV; if both less than r away from their respective axes, the the circle is in all four quadrants.

Could all four pulleys be placed on the same quadrant or in 2 adjacent quadrants and still be in equilibrium?

In order for there to be equilibrium, or balance, within quadrants, pulleys must be on opposite sides of the quadrant. If there are four pulleys in the same quadrant, there can be no equilibrium, nor can there be equilibrium if four pulleys are in adjacent quadrants.

Why do sin and cos differ by one half pie?

In math, the sine and cosine functions are one of the main trigonometric functions. All other trigonometric function can be specified within the expressions of them. The sine and cosine functions are exactly related and can be articulated within conditions of every other. Let us consider A be the angle sine can be identified as the ratio of the side opposite near to the angle toward the hypotenuse. Cosine of an angle is the ratio of the side adjacent to the angle A to the hypotenuse.
