Question 661761: Show that the equation below is NOT an identity.
Ösinē(q) + cosē(q) = sin(q) + cos(q)

Answer by Edwin McCravy(20056)   (Show Source): You can put this solution on YOUR website!
Ösinē(q) + cosē(q) = sin(q) + cos(q) 

To show that an equation is NOT an identity, you only need to 
show one case where the equation is NOT true.

Let's pick q = 30°

Ösinē(30°) + cosē(30°) = sin(30°) + cos(30°)

 =  + 

 =  + 

     =  + 

     1 = 1.366025404

That is certainly false.
