Question

Find the exact value of sin⁡(x+y)\sin\left(x+y\right). Use a trigonometric identity.cos⁡x=511\cos x=\frac{5}{11}, sin⁡y=−18\sin y=-\frac18, xx in fourth quadrant, yy in third quadrant

Accepted Answer

−5+124288\frac{-5+12\sqrt{42}}{88}

Answer

124271\frac{12\sqrt{42}}{71}

Answer

−124271-\frac{12\sqrt{42}}{71}

Answer

5−124288\frac{5-12\sqrt{42}}{88}

Find the exact value of sin(x+y)\(\sin\]\left\)(x+y\(\right\)). Use a trigonometric identity.cosx=511\(\cos\) x=\(\frac{5}{11}\), siny=−18\(\sin\) y=-\(\frac\)18, xx in fourth quadrant, yy in third quadrant

Find the exact value of $\sin (x + y)$ . Use a trigonometric identity.
$\cos x = \frac{5}{11}$ , $\sin y = - \frac{1}{8}$ , $x$ in fourth quadrant, $y$ in third quadrant
