How do I fix the error "Line 10: Parse error at 2: usage might be invalid MATLAB syntax"?

Vb=[0 -12];
Va=(-18*cosd(60)-18*sind(60));
Vba=Vb-Va;
magnitude_Vba=norm(Vba);
Angle_Vba=atand(Vba(2)/Vba(1));
Abnormal=Vb(2)^2/100;
Ab=(-Abnormal-3);
Aa=2*cosd(60) 2*sind(60);--- this line is getting the error
Aba=Ab-Aa;
magnitude_Aba=norm(Aba);
Angle_Aba=atand(Aba(2)/Aba(1));

What is unclear about the error message? Clearly you're missing something between 2*cosd(60) and 2*sind(60), perhaps an operator. As it is, yes the line does not make sense.

You either need an arithmetic operator (addition, subtraction, muyltiplication, division or the element-wise vectorized versions of them) or create ‘Aa’ as a matrix.
Assuming you want it as a matrix, this will work:
Aa = [2*cosd(60) 2*sind(60)]; % --- this line is getting the error
and will work with the rest of your code (producing Angle_Aba=48.6), although I have no idea what you actually want to do.

Well, yes, since Aba has only one element, Aba(2) doesn't exist.
Clearly, you've made another mistake. Perhaps you should proofread your code.

Exactly.
What are your data, and what do you want to do with them?
