1. Start with the right-hand side of the equation: \csc x + \cot x
2. Express \csc x \cot x
\csc x = \frac{1}{\sin x}
\cot x = \frac{\cos x}{\sin x}
3. Add the fractions:
\csc x + \cot x = \frac{1}{\sin x} + \frac{\cos x}{\sin x} = \frac{1 + \cos x}{\sin x}
4. The expression \frac{1 + \cos x}{\sin x}
Therefore, the identity is valid:
\frac{1 + \cos x}{\sin x} = \csc x + \cot x
2. Express
3. Add the fractions:
4. The expression
Therefore, the identity is valid:
