Answer:

13 = u

Step-by-step explanation:

Please include the instructions. I'm assuming you are to "solve for u."

Dividing both sides by 2, we get:

3u + 7 = -2(3 - 2u), or 3u + 7 = -6 + 4u. Combine like terms.

Then 13 = u

Cscθ - sinθ = _____

galina1969 [7]

So you maybe know that $\csc x = \frac{1}{\sin x}$ . Now let us try to simplify the expression

$\csc x - \sin x = \frac{1}{\sin x} - \sin x = \frac{1}{\sin x} - \frac{\sin^2 x }{\sin x}=\frac{1-\sin^2 x}{\sin x} =$

$= \frac{\cos^2 x}{\sin x} = \cot x \cdot \cos x$
