The ONLY place where that is true is where angle A is 0 degrees and 90 degrees. It is false everywhere else.

Why did Franck Z get a thumbs down? Pi *does* work.

sin(pi) = 0
cos(pi) = -1

So, sin(pi)+cos(pi) = -1.

pi radians = 180 degrees.

Type "sin(pi)+cos(pi)" into Google and see.

Try with Pi.

(ps : thank you eta_muons)
