TBQ - Prove the following IV — task. Maths TNSB Mentoring, Class 10 Crash course.

Establish that \(\frac{sin \ X}{1 + cos \ X}\) \(=\) \(\frac{1 - cos \ X}{sin \ X}\)

Proof:

\(LHS =\) \(\frac{sin \ X}{1 + cos \ X}\)

\(=\)

\(= RHS\)

Hence, we proved.

Answer variants:

\frac{\sin X (1 - \cos X)}{1^{2} - \cos^{2} X}

\frac{\sin X}{1 + \cos X} \times \frac{1 - \cos X}{1 - \cos X}

\frac{\sin X (1 - \cos X)}{\sin^{2} X}

\frac{1 - \cos X}{\sin X}
