Okay, this is gonna be the calculus AB test questions number nine and ten. Question number nine asks us to integrate the function (4/(1+x^2)) dx from -1 to 1. To make the function more recognizable, we can factor out the 4. We also know the antiderivative formula for (1/(1+x^2)) is arctan(x). So, when we evaluate the integral, we get arctan(1) - arctan(-1). Arctan(1) is equal to π/4, while arctan(-1) is equal to -π/4. Therefore, the answer is 2π/4, which simplifies to π/2. Moving on to question number ten, we have the function f(x) = cos^2(x). We want to find the value of f double prime. Firstly, let's rewrite the function as f(x) = cos(x^2). Taking the derivative using the chain rule, we get 2cos(x)(-sin(x^2)), which simplifies to -2cos(x)sin(x^2). Now, we need to take the second derivative using the product rule. We can separate the -2cos(x) and sin(x^2) as two separate terms. Evaluating the derivative, we get (-2sin(x))(sin(x^2)) + (-2cos(x))(2x*cos(x^2)). Simplifying further, we have -2sin(x)sin(x^2) - 4xcos^2(x^2). And that is the value of f double prime.
