• Quadrant-based signs of sin, cos, tan
• Reference angles and symmetry (sin(180° – x) = sin x, etc.)

• Practice regularly, using a variety of exercises and resources.
• Focus on understanding the concepts and formulas, rather than just memorizing them.
• Apply trigonometric concepts to real-world problems, such as physics, engineering, and navigation.

Hint:

(\cos^2 \alpha = 1 - \sin^2 \alpha). Pay attention to the sign in Quadrant II (cosine negative).
