Answer:
Explanation:
To prove that the equation sin(x) = 0.3 has at least one solution, we can use the Intermediate Value Theorem.
1. The Intermediate Value Theorem states that if a continuous function takes on two different values at two different points, then it must also take on every value between those two points.
2. The function sin(x) is a continuous function.
3. The value 0.3 is between -1 and 1, which are the range of values of the sine function.
4. Therefore, by the Intermediate Value Theorem, there must exist at least one value of x for which sin(x) = 0.3.
In other words, the equation sin(x) = 0.3 has at least one solution.
