To find the exact values of cosθ, cscθ, and tanθ for the point (-3, 2), one must first determine the lengths of the sides of the right triangle formed by this point in relation to the origin. The hypotenuse can be calculated using the Pythagorean theorem, yielding a length of √13. From this, cosθ is found as adjacent/hypotenuse, giving -3/√13, while cscθ is the reciprocal of sinθ, calculated as hypotenuse/opposite, resulting in √13/2. Finally, tanθ is derived as opposite/adjacent, resulting in -2/3. This method effectively provides the exact trigonometric values based on the coordinates of the point.
