Suspect it should be sind() and cosd() ?:
R= 40;
Xo= 125;
B = 42;
Kone = 5;
T = 0:30;
% v-----------------------------v-----missed it
xT =(5*(cos(45)+B*(T+Kone).*sin(T)/2+sin(45)+B*(T+1/Kone).*cos(T)))
% ^---- was the reason for your error
% v-----------------------------v-----missed it
yT =(5*(sin(45)+B*(T+Kone).*sin(T)/2-cos(45)+B*(T+1/Kone).*cos(T)))
% ^---- was the reason for your error
plot (xT,yT,'r--')
