The degree 1st Year 1st sem math exam covers a broad range of topics, including calculus, algebra, trigonometry, and geometry. It can be challenging to prepare for this exam, but with the right guidance, you can score well.

The first step towards preparing for the exam is to understand the syllabus and exam pattern. The exam will consist of both objective and subjective questions. To score well, you need to have a good understanding of the concepts and be able to apply them to solve problems. Here are some important questions that will help you prepare for your degree 1st Year 1st sem math exam.

**Important Questions**

- What is the value of sin 45° + cos 45°?
- Evaluate lim (x->0) (sin x)/x.
- Find the domain of the function f(x) = √(x^2 – 4).
- Find the derivative of f(x) = x^3 – 3x^2 + 2x – 1.
- Solve the equation 3x + 4 = 2x + 9.
- Find the value of tan (pi/4 – theta).
- Find the area of a triangle with sides 5 cm, 6 cm, and 7 cm.
- Find the equation of the line that passes through points (2, 3) and (4, 5).
- Evaluate ∫(1/x) dx.
- Find the value of log 1000.

**Explanation and Solution**

- The value of sin 45° + cos 45° is (√2/2) + (√2/2) = √2.
- Using L’Hospital’s rule, we get lim (x->0) (sin x)/x = lim (x->0) cos x = 1.
- The domain of the function f(x) = √(x^2 – 4) is (-∞, -2) U (2, ∞).
- The derivative of f(x) = x^3 – 3x^2 + 2x – 1 is f'(x) = 3x^2 – 6x + 2.
- Solving the equation 3x + 4 = 2x + 9, we get x = 5.
- Using the identity tan (pi/4 – theta) = (1 – tan theta)/(1 + tan theta), we get the value of tan (pi/4 – theta) as (1 – tan theta)/(1 + tan theta).
- Using Heron’s formula, we get the area of the triangle as √(9
*4*3*2) = 6
