Differentiate((a*e^(2x)+b*e^(3x)*Cos(2x)+c*e^(3x)*Sin(2x)),x) comes up with Error: Dimension mismatch
Dimension
mismatch error occurs when arguments are not with same dimensions. Two or more arguments must be of the same
dimension. For example, [1,2]+[1,2,3] is a dimension mismatch because the matrices
contain a different number of elements. By the way, it it very easy to resolving
your problem with differentiation. See captured image
As a result of differentiation you had to obtained:
(3b+2c)cos2x+(3c-2b)(sin2x)e^(3x)+2ae^(2x)

Correction of the result. You had to obtained:
((3b+2c)cos2x+(3c-2b)sin2x)e^(3x)+2ae^(2x)
Correction of the result. You had to obtained:
((3b+2c)cos2x+(3c-2b)sin2x)e^(3x)+2ae^(2x)

SOURCE: I try to install software
I do not know the program you installed, so I will skip the part.
As to the derivative of the sine function, your result is correct if the angle unit is degree.
d(sin(x))/dx = cos(x) is true only if the angle unit is the radian. In degrees, you would have a factor Pi/180 which is 0.174532925. I suggest you consult a calculus book to understand where that factor comes from.
