it would be secant, 1/cosine Y equals 2x and y equals 2x-1? Which means 0 = -1! What is cosine to the negative first power? [ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ) Related questions Why does sec 0 equals 1? Secant is 1 over cosine...

The goodness of the fit of model predictions to the data was estimated by an R2 statistic which is the proportion of the variance accounted for by the fit, adjusted by the number of free parameters (Judd & McClelland, 1989). The R2 value was calculated as follows:(4)R2=1-∑i=1nαi...
It is also interesting that the division property given by: xnxm=xn−m,x≠0 may help us understand what happens when n=m, in other words, when n−m becomes equal to zero.Answer and Explanation: Zero is a very interesting number. This is also true when it is used as an exponent...
