What is the function of the expression x^3 + 8?

The expression x3 + 8 describes a mathematical function, specifically a polynomial function. To better understand its properties, we can break this down. This expression can be rewritten as: x3 + 23 Recognizing this as a sum of cubes allows us to apply the sum of cubes formula, which states: a3 + b3 = (a … Read more

What is the exact value of arctan(sin(p/2)) and how do we arrive at that conclusion?

To find the exact value of arctan(sin(p/2)), we first need to evaluate sin(p/2). The angle p/2 (or π/2 in radians) corresponds to 90 degrees. The sine of 90 degrees is one of the fundamental values in trigonometry, which is: sin(π/2) = 1 Now, substituting this back into our original expression: arctan(sin(π/2)) = arctan(1) The arctan … Read more
