Question

value of sin30-cos 60

Answer 1

Answer ⇒ Zero (0)

_____________________________

Step-by-step explanation ⇒ We know that the Value of the Sin30° is 1/2 and also, the value of the Cos60° is 1/2.

Thus, By substituting this we will get,

Sin30 - Cos60 = 1/2 - 1/2

= 0

______________________________

Also, It can be done by the method of the complementary angles.

Sin30° - Cos60°  = Sin30° - Cos(90°-30°)   [Since, Sinθ = Cos(90 - θ)]

= Sin30° - Sin30°

= 0

Answer 2

Hey there!

Answer:

0

Step-by-step explanation:

sin 30° - cos 60°

= 1/2 - 1/2     ( ∵ sin 30° and cos 60° = 1/2)

= 0
