question:
Inflight smoking is prohibited by almost all airlines. Smoking on domestic U.S. airliners, for instance, was banned on all domestic flights with a duration of two hours or less beginning in 1988, with all planes being smoke-free by the end of the 1990s. According to FAA regulations, smoking lit cigarettes or anything else that produces smoke or flame is prohibited onboard most commercial aircraft. As of October 2015, the USDOT prohibits the use of electronic cigarettes on flights, as well as such devices from being transported in checked luggage.
answer:
are there any smoking flights in the world?


question:
In mathematics and vector algebra, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional space ( R 3 ) (\displaystyle \left(\mathbb (R) ^(3)\right)) and is denoted by the symbol × (\displaystyle \times ) . Given two linearly independent vectors a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) , the cross product, a × b (\displaystyle \mathbf (a) \times \mathbf (b) ) , is a vector that is perpendicular to both a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) and thus normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. It should not be confused with dot product (projection product).
answer:

is dot product the same as cross product?
