    Find absolute minimum of f(x)=sin(x)-cos(x) on [0,pi]

    Theyre both equal to root 2 / 2 so now you have: root 2 / 2(sinx - cosx) But I'm failing to see where to go from that. Do you equate it to 0 and then get x=0 or 1?

    Find absolute minimum of f(x)=sin(x)-cos(x) on [0,pi]

    Yup, I read that as something else, not sure what but thank you nonetheless.

    Find absolute minimum of f(x)=sin(x)-cos(x) on [0,pi]

    sin(x)cos(pi/4) - sin(pi/4)cos(x) I feel like I'm missing something really obvious here.

    Find absolute minimum of f(x)=sin(x)-cos(x) on [0,pi]

    Homework Statement Find the absolute minimum of f(x)=sin(x)-cos(x) on [0,pi] Homework Equations - The Attempt at a Solution I know the answer is 0 from looking at a graph, but I cannot figure out how to express my workings algebraically. The end goal of this is to do a presentation on how I...
