1 ) Value of - tan²60° +4cos²45° +3cosec²60° + 2 cos²90°
2 ) Value of 2 cosec30° + 3sec 60° - 7/ 3cot²30°
1) Answer →
We know that value of
tan 60° = √3
cos 45° = 1/√2
Cosec 60° 2/√3
Cos 90° = 0 .
Putting these values in the question -
3 + 2 + 2
→ 6
2) Answer →
We know that value of -
Cosec 30° = 2
sec 60° = 2
cot 30° = √3
Putting these values in question -
2 (2) +3(2) -7/3(√3)²
4 + 6 -7
→ 3
