Problem 23
Question
Find a cofunction with the same value as the given expression. $$\csc 25^{\circ}$$
Step-by-Step Solution
Verified Answer
\( \sec 65^{\circ} \)
1Step 1: Identify the Cofunction
A cofunction for cosecant (\( \csc \)) is secant (\( \sec \)).
2Step 2: Calculate the Complement
The complement of the angle is \( 90^{\circ} - 25^{\circ} = 65^{\circ} \).
3Step 3: Apply the Cofunction
Thereby using the complementary angle in the cofunction gives \( \sec 65^{\circ} \).
