matlabのsymbolic math toolboxで時間微分したいときはどのようにコマンドを打ち込んだらいいのでしょうか? 例えば、rsinθ という関数を微分したときに, r dθ cosθ のように表現したいです。

Approximate translation:
When you want to differentiate time with matlab 's symbolic math toolbox, how do you input a command? For example, when differentiating the function r sin θ, I want to express it as r d θ cos θ.

syms r theta
f(r,theta) = r * sin(theta)
diff(f, theta)
