Question

2cos60°+√3 sin60° обчислити

Answer 1

Відповідь:

2cos60° + √3sin60° = 2·1/2 + √3·√3/2 = 1 + 3/2 = 5/2 = 2 1/2.

Answer 2

To calculate the value of the expression 2cos60° + √3sin60°, we can use the trigonometric identities for cosine and sine.

cos(60°) = 1/2 sin(60°) = √3/2

Substituting these values into the expression, we have:

2cos60° + √3sin60° = 2(1/2) + √3(√3/2) = 1 + 3/2 = 1 + 1.5 = 2.5

Therefore, 2cos60° + √3sin60° equals 2.5.
