Trigonometric Ratios and the Unit Circle - Joseph English

Witryna5 wrz 2015 · As you can see, sin (θ) = y/1 = y. This is why the y-coordinate is the sin value. I thought someone would answer with this reasoning. It seems reasonable to … WitrynaA unit circle chart is a 1-unit radius circle with a center (0, 0) of the Cartesian plane used in trigonometry to determine the sine and cosine values of angles. In the circle, y (or the reading on the y axis) = sin (θ) and X (or the reading on the X-axis) = cos (θ). Some angles to the origin center share trigonometric values. ガス給湯器 価格
