I need quick help here please tutor. Question 1
Transcribed Image Text:**Trigonometric Identities**
For problems 1-3, prove the given identity.
1. \( \tan(-x) \cos x + \csc x \sin x = 1 - \sin x \)
2. \( \frac{\sec x}{\cos x} - \frac{\ln x}{\cot x} = 1 \)
These problems require the use of trigonometric identities and transformations to verify the equations provided. An understanding of fundamental identities like \(\tan(-x) = -\tan x\) and \(\csc x = \frac{1}{\sin x}\) will be helpful in these proofs.
