(tan(x) + cot(x))*sin(2*x) при x = -3/2

(tan(x) + cot(x))*sin(2*x)

$$\left(\tan{\left (x \right )} + \cot{\left (x \right )}\right) \sin{\left (2 x \right )}$$

(tan((-3/2)) + cot((-3/2)))*sin(2*(-3/2))

$$\left(\tan{\left ((-3/2) \right )} + \cot{\left ((-3/2) \right )}\right) \sin{\left (2 (-3/2) \right )}$$

(tan(-3/2) + cot(-3/2))*sin(2*(-3)/2)

$$\left(\tan{\left (- \frac{3}{2} \right )} + \cot{\left (- \frac{3}{2} \right )}\right) \sin{\left (\frac{-6}{2} \right )}$$

-(-cot(3/2) - tan(3/2))*sin(3)

$$-1 \left(-1 \tan{\left (\frac{3}{2} \right )} + -1 \cot{\left (\frac{3}{2} \right )}\right) \sin{\left (3 \right )}$$
