I really don't consider myself good at calculus at all, but isn't that what i did? to find derivative of cos(30 - x) when x and '30' are both in degrees.. = cos(∏/6 - ∏/180(x)) now to find derivative.. =-sin(∏/6 - ∏/180(x)) * (-∏/180) =∏/180*sin(∏/6 - ∏/180(x)) ?

What do you mean 'formally'? If they are not in radians when I get to the chain rule, this will happen derivative of cos(30 - theta) = -sin(30 - theta) * (-1) = sin(30 - theta) but if I convert to rads.. derivative of cos(∏/6 - ∏/180(theta)) = -sin(∏/6 - ∏/180(theta)) * (-∏/180) = ∏/180...

Hi all, The following is part of a part, of an assignment for my MATLAB course for uni. For most of the ODE solvers in MATLAB you also have to be able to solve the question numerically - and this is the component of the question I'm doing here.. The equilibrium equation of an arch...
