Final answer:
Cross multiplying for sin is a technique used to solve equations involving trigonometric functions.
Step-by-step explanation:
Cross multiplying for sin is a technique used to solve equations involving trigonometric functions. It involves multiplying the numerator of one fraction by the denominator of the other fraction and vice versa. Here's an example:
If we have the equation sin(x)/cos(x) = 2/3, we can cross multiply to get sin(x) * 3 = 2 * cos(x).
By using trigonometric identities and simplifying, we can solve for x.
