I am trying to input the formula that is shown in the picture...however I get an error
Error: File: lastPROBLEM.m Line: 3 Column: 78 Expression or statement is incorrect--possibly unbalanced (, {, or [.
I'm not sure what to do. Here is my current code
v = (-2*(exp(-2*t)).*cos(2*3.14*10*t)-((20*3.14*sin(2*3.14)(10)*t)*exp(-2*t))
I know it's not very neat and probably a headache to look but am really confused as to where the brackets are wrong?

First, count the parentheses to be sure they match.
Second, be sure there are operators (for example: addition, subtraction, multiplication, division) where necessary, since MATLAB does not assume operators where none are specified.

Try this
>> t = 1:4;
>> v = -2*(exp(-2*t)).*cos(2*pi*10*t) - 20*pi*sin(2*pi*10*t).*exp(-2*t)
v =
-0.2707 -0.0366 -0.0050 -0.0007
