Aug 22, 2016 · sin0˚ = 0 By the unit circle: As you can see, pairs are ordered in the manner of (cos,sin). In other words, the x value is cos and the y value is sin. Since in this problem we're dealing with the sine function, you can ask yourself: What is the y-value at 0˚? Well, the point at 0˚ is (1, 0), and the y value here is 0. The hypotenuse, although measuring 1 unit, doesn't matter, …

Jul 4, 2015 · sin x = 0 On the trig unit circle, the value sin x is the projection of an variable arc AM = x on the vertical axis OBy. When the arc = 0, the projection is also zero -> sin x = 0.

May 24, 2016 · If you know that #sinx = 0#, t Then you need to use a process called 'arcsin'. It might be shown as "arcs" or "asin" or similar.

Feb 17, 2018 · Use the unit circle to evaluate it to be 0. (This one's from Wikipedia, but any version of it will be more or less the same.) On the unit circle, the x-coordinate at each position is the cosine of the given angle, and the y-coordinate is the sine. For theta = 0, the rightmost point, the coordinate pair is (1, 0). The y-coordinate is 0, so sin(0) = 0. If you're not at the point where …

Feb 3, 2015 · The sine function equals 0 for every multiple of pi~~3.14 graph{sinx [0, 7, -1.2, 1.2]} pi radians is equal to 180^0 The sine-function goes from 0 to 1 at 90^0=pi//2 And then back to 0 at 180^0=pi Down to -1 at 270^0=3pi//2 And up to 0 again at 360^0=2pi So it will be 0 at every multiple of pi Summary sin x=0 ->x=k*pi, with k any whole number

May 29, 2016 · Consider the rule C-A-S-T or All Slow Turtles Crawl for this type of problem. Both of these rules indicate in which quadrant the trigonometric function is positive. In all quadrants except the first, only 1 out of the three trigonometric functions are positive; the other two are negative. Quadrant 1: All are positive Quadrant 2: Sine is positive Quadrant 3: Tangent is …
