Which number is bigger, $\sin 1-\cos 1$ or $\dfrac{1}{4}$?
 
Mathematics news on Phys.org
Is the answer $sin1 - cos1$
 
What does a calculator give for sin(1)- cos(1)?
 
I don't know I just used expansion for this.

Yeap!(Cool) For your information, a challenge problem posted in this sub forum is meant for the interested members to post not only the final answer, but also the method of solving as well. (Nod)
