In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.
Scalar multiplication of two vectors (to give the so-called dot product) is commutative (i.e., aÂ·b = bÂ·a), but vector multiplication (to give the cross product) is not (i.e., a Ã b = âb Ã a). The commutative law does not necessarily hold for multiplication of conditionally convergent series.
The commutator subgroup can also be defined as the set of elements g of the group which have an expression as a product g = g 1 g 2 ... gk that can be rearranged to give the identity.he commutator subgroup can also be defined as the set of elements g of the group which have an expression as a product g = g 1 g 2 ... gk that can be rearranged to give the identity.
