Studdy Solution

STEP 1

1. The problem involves a trigonometric identity.
2. The identity $\sin^2 \alpha + \cos^2 \alpha = 1$ is fundamental in trigonometry.

STEP 2

1. Recognize the trigonometric identity.
2. Determine the value of $k$ .

STEP 3

Recognize that the expression $\sin^2 \alpha + \cos^2 \alpha$ is a well-known trigonometric identity. According to this identity:
$\sin^2 \alpha + \cos^2 \alpha = 1$

STEP 4

Since $\sin^2 \alpha + \cos^2 \alpha = 1$ , the value of $k$ is:
$k = 1$
The value of $k$ is:
$\boxed{1}$
