Pre Calculous Unit Circle Project Questions

Explain what a radian mensurate represents using the building block of measurement round of drinks as a reference. A radian measure represents the distance of a radius on the whole batch from the positive x-axis.  Radians atomic number 18 broadly associated with pi.   2) How do special function tri cants directly relate to the hook circle?  There are twain types of special chasten triangles: 45-45-90 and          30-60-90.  The legs on a 45-45-90 triangle are 1 and 1 and the hypotenuse is the square group of 2.  The legs on a 30-60-90 triangle are 1 and the square reference of 3 and the hypotenuse is 2.  If you were to take the leash trigonometric functions of either 45 item angle, you would stick the (square root of 2)/2 for both co sin (x) and sine (y) and 1 for tangent (y/x).  If you were to take the three trigonometric functions of the 30 level angle, you would cast down the (square root of 3)/2 for cosine, ½ for sine and the (square root o f 3)/3 for tangent.  If you were to take the three trigonometric functions of the 60 degree angle, you would get ½ for cosine, the (square root of 3)/2 for sine and the square root of 3 for tangent.     3) Suppose that you did not cede the unit of measurement halt me drug on Circle A, but rather of a circle of radius 5.  Will the angle measures in degrees and/or radians deepen?  Why or why not?

 No, uncomplete of the angle measures leave behind change because the radius, no matter the length, has no ready on the angle measures.   4) Suppose that you did not have the Unit Circle on Circle A, but rath er of a circle of radius 5.  What do you su! ppose the x- and y-coordinates will be for that circle for Quadrant I?  The coordinates for 0 radians would be (5,0).  The coordinates for ?/4 radians would be [(square root of 2)/2, (square root of 2)/2].  The coordinates for ?/2 radians would be (0,5).       5) analyze the two points in Quadrant I on Circle B.  What is the special relationship amongst them? (Consider the relationship between the angles whose ending sides pass through these points.)  If you refer to Circle B, the two...If you indigence to get a full essay, order it on our website: BestEssayCheap.com
