Unformatted text preview: alpha = x(1); beta = x(2); d1 = 1.2; d2 = 1.2; a = (-d1*sin(alpha))-(d2*sin(alpha+beta)); b= -d2*sin(alpha + beta); c= d1*cos(alpha)+d2*cos(alpha+beta); d= d2*cos(alpha + beta); jacobian = [ a , b ; c , d ]; 7.8)a) Used values [ 1, 1] the m file returned the values alpha = -3.9999 and beta = 103.425 b) Bad values that I used were [5, 6 ] each caused Newton’s method to fail....
