Question

Anwer of 2cos60°sin30°

Answer 1

`2 \cos(60) \sin(30)`

`\cos(60) = (1)/(2)`

`\sin(30) = (1)/(2)`

`2 * (1)/(2) * (1)/(2)`

`2 * (1)/(4)`

`(1)/(2)`

Answer 2

`(1)/(2)`

Explanation:

Using exact values from the 30- 60- 90 special triangle

2cos60°sin30°

= 2 ×
`(1)/(2)` ×
`(1)/(2)` = 1 ×
`(1)/(2)` =
`(1)/(2)`
