We'll work through some examples and exercises to solidify our understanding of the concepts we've discussed. Let's start with an algebraic example. Suppose problem 14 involves solving the equation 2x + 5 = 11. The first step is to isolate the variable. We can do this by subtracting 5 from both sides of the equation: 2x = 6. Then, we can divide both sides by 2 to get x = 3. It's like peeling an onion, layer by layer, until you get to the core. Let's try another one. Suppose problem 15 involves solving the inequality 3x - 2 < 7. We can add 2 to both sides to get 3x < 9. Then, we can divide both sides by 3 to get x < 3. Remember to pay attention to the direction of the inequality sign. It's like navigating a one-way street – you need to follow the signs. Now, let's look at a geometric example. Suppose problem 14 involves finding the area of a triangle with base 10 and height 6. The formula for the area of a triangle is (1/2) * base * height. So, the area of this triangle is (1/2) * 10 * 6 = 30. It's like using a recipe to bake a cake – you need to follow the formula to get the right result. Suppose problem 15 involves finding the circumference of a circle with radius 4. The formula for the circumference of a circle is 2 * pi * radius. So, the circumference of this circle is 2 * pi * 4 = 8pi. Remember to use the appropriate formula for each shape. It's like choosing the right tool for the job. Let's try an example that might involve calculus. Suppose problem 14 involves finding the derivative of the function f(x) = x^2 + 3x - 2. The derivative of x^2 is 2x, the derivative of 3x is 3, and the derivative of a constant is 0. So, the derivative of f(x) is f'(x) = 2x + 3. It's like understanding the rules of differentiation. Suppose problem 15 involves finding the integral of the function g(x) = 2x - 1. The integral of 2x is x^2, and the integral of -1 is -x. So, the integral of g(x) is G(x) = x^2 - x + C, where C is the constant of integration. Remember to add the constant of integration when finding indefinite integrals. It's like remembering to put the lid on the jar. By working through these examples and exercises, you'll gain confidence in your problem-solving abilities.
