Answer: y−3=−3y−43
Step 1: Add 3y to both sides.
y−3+3y=−3y−43+3y
4y−3=−43
Step 2: Add 3 to both sides.
4y−3+3=−43+3
4y=−40
Step 3: Divide both sides by 4.
4y

Answer:
Step-by-step explanation:
Recall the formula for the sine of the double angle:
we know that 
, and that 
is in the interval between 0 and 90 degrees, where both the functions sine and cosine are non-negative numbers. Based on such, we can find using the Pythagorean trigonometric property that relates sine and cosine of the same angle, what 
is:
With this information, we can now complete the value of the sine of the double angle requested:
