Verify the identity

Answer:

We have to prove

sin⁡(α+β)-sin⁡(α-β)=2 cos⁡ α sin ⁡β

We will take the left hand side to prove it equal to right hand side

So,

=sin⁡(α+β)-sin⁡(α-β) Eqn 1

We will use the following identities:

sin⁡(α+β)=sin⁡ α cos⁡ β+cos⁡ α sin⁡ β

and

sin⁡(α-β)=sin⁡ α cos ⁡β-cos ⁡α sin ⁡β

Putting the identities in eqn 1

=sin⁡(α+β)-sin⁡(α-β)

=[ sin⁡ α cos ⁡β+cos⁡ α sin⁡ β ]-[sin⁡ α cos ⁡β-cos ⁡α sin ⁡β ]

=sin⁡ α cos⁡ β+cos⁡ α sin ⁡β- sin⁡α cos⁡ β+cos ⁡α sin ⁡β

sin⁡α cos⁡β will be cancelled.

=cos⁡ α sin ⁡β+ cos ⁡α sin ⁡β

=2 cos⁡ α sin ⁡β

Hence,

sin⁡(α+β)-sin⁡(α-β)=2 cos ⁡α sin ⁡β

Answer:

Step-by-step explanation:

hello :

X/2 + 3/8 = 1

X/2 + 3/8 -3/8= 1-3/8

X/2 = 5/3 means : 3x=10 so : x=10/3

The answer to the above math expression is . See the computation below.

<h3>What is the calculation justifying the above?</h3>

First we solve for the numerator. The numerator is:

7√2 - 2√16

Where:

7√2 = 9.89949493661; and

2√16 = 8

Hence,

7√2 - 2√16 = 1.89949493661

Next we solve for the denominator. This is given as:

3√8=8.48528137424

Hence,

(7√2 - 2√16)/3√8 = 1.89949493661/8.48528137424

= 0.22385762508

$\approx$ 0.224
