Question

Evaluate sin2600
- 2tan45

- cos230​

Answer 1

Step-by-step explanation:

'ur ques is wrong yaar'

sin²60⁰- 2tan 45 - cos²30

sin 60 = √3/2

tan 45 = 1

cos 30 = √3/2

substituting the values

=>(√3/2)² - 1 - (√3/2)²

=>3/4 - 1 - 3/4

=>2

:. therefore the value of sin²60⁰- 2tan 45 - cos²30 is 2
