Question

The value of Sin²30° +Cos²45° +4Cot²60° -2Sin²90° is
​

Answer 1

Answer:

Sin²30° +Cos²45° +4Cot²60° -2Sin²90° is

= 1/4 + 1/2 + 4/3 - 2

= (3+6+16-12)/12

= 13/12

Step-by-step explanation:

Sin²30° = (1/2)² = 1/4

Cos²45° = (1/root2)² = 1/2

4Cot²60° = 4 × (1/root3)² = 4/3

2sin²90° = 2 × 1² = 2
