Review the steps of the proof of the identity
koban [17]

Answer:

step 2

and then also in step 3 compensating the error in step 2

Step-by-step explanation:

I think I just answered this for another post.

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

so, step 1 is correct :

sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)

but step 2 suddenly and incorrectly switched that central "-" to a "+".

yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.

then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.

How would I finish solving this?
Zarrin [17]
Hello!

The original equation is:

200 = (5w ÷ 2)8

This problem can be written as:

200 = (5w/2)8

And you can then reduce the numbers with 2:

200 = 5x * 4
200 = 20x
10 = x

Your correct answer is 10.
