    5 days ago · Introduction to Coordinate Trigonometry. Armed with our knowledge from the previous chapter, we now define the trigonometric functions.We will be viewing the trigonometric functions from three different perspectives in this course - coordinate trigonometry, right triangle trigonometry, and unit circle trigonometry. 1 For the most part, each perspective is mathematically equivalent to the others; however, each has an inherent weakness as a standalone perspective of the trigonometric functions.

    6 days ago · Definition: Quadrants in the Coordinate Plane—Points. For any positive real numbers 𝑥 and 𝑦, we say that (𝑥, 𝑦) lies in the first quadrant; (− 𝑥, 𝑦) lies in the second quadrant; (− 𝑥, − 𝑦) lies in the third quadrant; (𝑥, − 𝑦) lies in the fourth quadrant. Points on the axes are not said to lie in any quadrant.
