Should I use input as radian to estimate root of $f(x)=x^2-\sin x$ by bisection method?

Question

I want to estimate roots of $f(x)=x^2-\sin x$(first root is obviously $x_1=0$ and second root is in the interval $[0.5,1]$ ) using bisection method.

We have trigonometry function $\sin x$ and ordinary function $x^2$ . so my question is should I put inputs as radians (for example calculate $f(\frac{\pi}{4})$) or I should use numbers (for example calculate $f(1)$ )?
