The correct Answer is:
To find the value of the product \( \cos 0^\circ \cos 1^\circ \cos 2^\circ \ldots \cos 179^\circ \cos 180^\circ \), we can follow these steps: ### Step 1: Understand the cosine function The cosine function, \( \cos \theta \), is defined for angles from \( 0^\circ \) to \( 180^\circ \). Notably, \( \cos 90^\circ = 0 \). ### Step 2: Identify the product We are looking at the product: \[ P = \cos 0^\circ \cos 1^\circ \cos 2^\circ \ldots \cos 179^\circ \cos 180^\circ \] ### Step 3: Notice the presence of \( \cos 90^\circ \) In the product, we can see that \( \cos 90^\circ \) is included. Since \( \cos 90^\circ = 0 \), this means that the entire product will be zero because multiplying any number by zero results in zero. ### Step 4: Conclude the result Therefore, we can conclude that: \[ P = 0 \] ### Final Answer The value of \( \cos 0^\circ \cos 1^\circ \cos 2^\circ \ldots \cos 179^\circ \cos 180^\circ \) is \( 0 \).
