Trigonometry Formulas for NEET

1. Pythagorean Identities:
- $\sin^2 x + \cos^2 x = 1$
- $1 + an^2 x = \sec^2 x$
- $1 + \cot^2 x = \csc^2 x$

2. Angle Addition and Subtraction Formulas:
- $\sin(A \pm B) = \sin A \cos B \pm \cos A \sin B$
- $\cos(A \pm B) = \cos A \cos B \mp \sin A \sin B$
- $ an(A \pm B) = \frac{ an A \pm an B}{1 \mp an A an B}$

3. Double Angle Formulas:
- $\sin 2A = 2\sin A \cos A$
- $\cos 2A = \cos^2 A - \sin^2 A$
- $ an 2A = \frac{2 an A}{1 - an^2 A}$

4. Half Angle Formulas:
- $\sin \frac{A}{2} = \pm \sqrt{\frac{1 - \cos A}{2}}$
- $\cos \frac{A}{2} = \pm \sqrt{\frac{1 + \cos A}{2}}$
- $ an \frac{A}{2} = \pm \sqrt{\frac{1 - \cos A}{1 + \cos A}}$

5. Trigonometric Ratios of Compound Angles:
- $\sin (A + B) = \sin A \cos B + \cos A \sin B$
- $\cos (A + B) = \cos A \cos B - \sin A \sin B$
- $ an (A + B) = \frac{ an A + an B}{1 - an A an B}$
These trigonometric formulas are essential for NEET preparation as they are frequently used in solving problems related to physics, chemistry, and mathematics. Understanding and memorizing these formulas will help you solve trigonometry problems efficiently and accurately during the exam. Practice applying these formulas to various types of trigonometric problems to enhance your problem-solving skills and boost your confidence for the NEET exam.
