Questions: Find the exact function value. csc(pi/4)

Transcript text: Find the exact function value. \[ \csc \frac{\pi}{4} \]

Solution

Step 1: Understand the Function

Recognize that \(\csc(\theta) = \frac{1}{\sin(\theta)}\).

Step 2: Find the Sine Value

For \(\theta = 0.785\), the \(\sin(\theta)\) value is directly known or derived from special triangles.

Step 3: Calculate the Reciprocal

\(\csc(\theta) = \frac{1}{\sin(\theta)} = \frac{1}{0.707}\).

Step 4: Simplify the Expression

After rounding, \(\csc(\theta)\) is approximately 1.414.
