How do you write a program to find cosx?

To write a program to find the cosine of an angle ( x ), you can use the built-in cosine function available in most programming languages. For instance, in Python, you can use the math library by importing it and then calling math.cos(x), where ( x ) should be in radians. If you have the angle in degrees, convert it to radians using math.radians(x). Here’s a simple example:

<code class="language-python">import math
x_degrees = 60 x_radians = math.radians(x_degrees) cosine_value = math.cos(x_radians) print(cosine_value)
