You asked:

Evaluate the expression: 12⋅11⋅14sin⁡(12.2)\frac{1}{2} \cdot 11 \cdot 14 \sin\left( 12.2 \right)

MathBot Answer:

12⋅11⋅14sin⁡(12.2)=77sin⁡(615)≈−27.58365473223576017224096475597451\frac{1}{2} \cdot 11 \cdot 14 \sin\left( 12.2 \right) = 77 \sin{\left(\frac{61}{5} \right)} \approx -27.58365473223576017224096475597451

12⋅11⋅14sin⁡(12.2)=112⋅14⋅sin⁡(12+210)=112⋅14⋅sin⁡(12+15)=112⋅14⋅sin⁡(615)=77⋅sin⁡(615)\begin{aligned}\frac{1}{2} \cdot 11 \cdot 14 \sin\left( 12.2 \right)& = \frac{11}{2} \cdot 14 \cdot \sin{\left(12 + \frac{2}{10} \right)}\\& = \frac{11}{2} \cdot 14 \cdot \sin{\left(12 + \frac{1}{5} \right)}\\& = \frac{11}{2} \cdot 14 \cdot \sin{\left(\frac{61}{5} \right)}\\& = 77 \cdot \sin{\left(\frac{61}{5} \right)}\end{aligned}
