WebMay 2, 2024 · The point (√2 2, − √2 2) is on the unit circle, as shown in Figure 5.3.3. Find sint, cost, tant, sect, csct, and cott. Figure 5.3.3. Solution. sint = − √2 2, cost = √2 2, tant = − 1, sect = √2, csct = − √2, cott = − 1. Example 5.3.2: Finding the … WebIn mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16, because 4² = (−4)² = 16. Every nonnegative real number x has a unique nonnegative square root, called the ...
