Answer 2

Let's simplify the given expression step by step:

1. First, we'll simplify each term separately:

   a) sin(π/4) = cos(π/4) = 1/√2 (This is a well-known trigonometric identity).

   b) tan(0) = 0 (The tangent of 0 degrees is 0).

   c) cot(π) = cot(180°) = 0 (The cotangent of 180 degrees is 0).

2. Now, let's plug in the values:

   sin(π/4) + cos(π/4) - tan(0) + cot(π) = (1/√2) + (1/√2) - 0 + 0

3. Combine like terms:

   (1/√2) + (1/√2) = 2/√2 = √2

So, the simplified expression is √2.
