Fill in the blank to complete the trigonometric formula -8sin(u)_(x)=(8sin(u))/(1+cos(u))

To complete the trigonometric formula, we need to find the correct expression for the left-hand side of the equation.Given: We can rewrite the left-hand side as: Now, we need to find the value of that makes the left-hand side equal to the right-hand side.To do this, we can equate the two expressions and solve for : Multiplying both sides by : Dividing both sides by : Multiplying both sides by : Solving for : Therefore, the completed trigonometric formula is: where .
