For two nonzero vectors a and b, this function can be calculated by dividing the dot product of a and b by the product of the norms of a and b.
For two nonzero vectors a and b, this function can be calculated by dividing the dot product of a and b by the product of the norms of a and b. The derivative of its inverse with respect to x is minus one over the square root of one minus x squared, and this function can be also stated as ½ of the quantity e to the ix plus e to the negative ix. FTP, what is this trigonometric function which can also be defined as the square root of one minus sine squared?
