5/3 cos(alpha) -5/2 cos(phi) + 11/6 cos(alpha - phi) = 0 a. solve the four-bar linkage problem for an input of alpha = 40 degree by interval halving. remember that the angles must be expressed in radians. let the initial value of phi be 30 degree. use a convergence criteria of epsilon = |phi_1 - phi_2| = 0.1. b. use newton's method to solve the four-bar mechanism. use the same initial conditions as for the interval halving. how many iterations to obtain the same value?

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
