What does "domain error an argument must be in a
The expression a function acts on (i.e. what is inside the function) is called its argument. The arguments of some functions such as y=ax, y=ax^2 can have any real value. However some functions have arguments that must be in a specified domain: they are restricted to some specified intervals. For example y=square root (x) can act on any positive value, but if you feed it a negative value it is out of the correct domain.

I get -0.017453 as an answer to derivative of cos
The differentiation rules for trigonometric functions you have been taught (ex: derivative of sin(x) is cos(x) ) are correct if the angle unit is in radians. If you use any other angle units (ex: degrees, grads) there will be a conversion factor :derivative of sin(ax) with respect to x is a.cos(ax).
Hope that helps
