How do you evaluate cos 30? | Socratic
Evaluate the following: (i) sin 60° cos 30° + sin 30° cos 60° (ii) 2 tan² 45° + cos² 30° - sin² 60° (iii) cos 45°/(sec 30° + cosec 30°) (iv) sin 30° + tan 45° - cosec 60°/(sec 30° + cos 60° + cot 45°)
Ex 8.2, 1 Class 10 - Evaluate (i) sin 60° cos 30° + sin 30° cos 60°
