tan square 60 + 4 cos square 45 + cosec square 60 + 2 cos square 90 divided by 2 cosec 30 + 3sec 60 - 7 by 3 cot square 30 plz plz
Answers
tan²60° + 4 cos²45° + cosec²60° + 2cos²90°
__________________________________ = 2.1
2cosec30° + 3sec60° - 7/3 cot²30°
Step-by-step explanation:
For the given problem,
The values are
tan60° = √3
cos45° = 1/√2
cosec60° = 2/√3
cos90° = 0
cosec30° = 2
sec60° = 2
cot30° = √3
By subtituting these values in the question,
tan²60° + 4 cos²45° + cosec²60° + 2cos²90°
______________________________________
2cosec30° + 3sec60° - 7/3 cot²30°
(√3)² + 4(1/√2)² + (2/√3)² + 2(0)
= __________________________
2(2) + 3(2) - 7/3( √3)²
3 + (4/2) + (4/3)
= ______________
(4 + 6) - 7
3 + 2 + 1.3
= __________
10 - 7
= 6.3/3
= 2.1
Therefore, the simplified answer for the given question is 2.1
Answer:
the answer will be 2.1
Step-by-step explanation:
if we simplify it we get 6.3/3=2.1
