WebNov 27, 2024 · You have to be consistent with the argument of the trigonometric function. Is not that "Python accepts radians", all programming languages I know use radians by default (including Python).. If you want to get the derivative of 5 degrees, yes, first convert to radians and then use it as the argument of the trigonometric function. WebFeb 4, 2024 · Here we will use the logarithmic derivatives. Step 1: Let u=e sin x. We need to find du/dx. Step 2: Taking logarithm on both sides, we get. log e u = log e e sin x. ⇒ log e u = sin x log e e. ⇒ log e u = sin x as we know that log a a=1. Step 3: Differentiating we get that. d d x ( log e u) = d d x ( sin x)
