WebIn the third quadrant, all x and y values will be negative, so all sine and cosine values will be negative. Tangent will be positive because a negative divided by a negative is positive.) The final quadrant is the fourth quadrant, and there, all x values are positive, but all y values are negative, so sine will be negative, cosine will be ... WebAdjacent side = OQ = -5/10 = -0.5 (negative side of x axis) Hypotenuse = OR = 1 (take radius to be positive) We then approximate the trigonometric ratios in the second quadrant. It can be confirmed from tables that these are better approximations. We see that the cosine and tangent are negative in second quadrant while the sine is positive. china sideboard glass doors for sale https://amayamarketing.com
