Answer 1

sine Alfa cos beta

see in the given picture

in the following

Answer 2

Answer:

The value of  sin(α - β) = sinα cosβ      

Step-by-step explanation:

As per the question,

Given data of question is ,

cosα = 0

Now,

we have to find the value of sin(α - β).

According to the trigonometric formula of mathematics,

sin(α - β) = sinα × cosβ - cosα × sinβ

Substitute the value of cosα = 0 in above equation, we get,

sin(α - β) = sinα × cosβ - 0 × sinβ

               = sinα × cosβ

Hence, the value of  sin(α - β) = sinα cosβ
