question 5 (1 point)\nthe cast rule identifies positive primary trigonometric ratios for angles.\ntrue\nfalse

Brief Explanations:

The CAST rule (also known as the All - Students - Take - Calculus rule) is a mnemonic device used in trigonometry. It helps to identify the sign (positive or negative) of the primary trigonometric ratios (sine, cosine, tangent) for angles in different quadrants. In the first quadrant (All), all ratios are positive. In the second quadrant (Students), only sine is positive. In the third quadrant (Take), only tangent is positive. In the fourth quadrant (Calculus), only cosine is positive. So, it does identify the sign (which implies positive in the relevant quadrants for the ratios) of primary trigonometric ratios for angles.
