Question

sin30+cos60 find the value ​

Answer 1

Sin Values

= sin 0° = √(0/4) = 0

= sin 30° = √(1/4) = ½

= sin 45° = √(2/4) = 1/√2

= sin 60° = √3/4 = √3/2

= cos 90° = √(4/4) = 1

Cos Values

= cos 0° = √(4/4) = 1

= cos 30° = √(3/4) = √3/2

= cos 45° = √(2/4) = 1/√2

= cos 60° = √(1/4) = ½

= cos 90° = √(0/4) = 0

Substitute the value of sin 30° and cos 60° value we get

= sin 30° + cos 60°

= 1/2 + 1/2

= 1
