Homework Statement
Prove sinx+cosx=x has a single solution in [0, pi/2]
The Attempt at a Solution
This question seems very strange to me. How can I prove there is a single solution for every number between 0 and pi/2?
I'm not sure what formula to use.
I'm learning infinitesimal math.
Can someone help me out?
Thanks!
