Question

If the equation sinx+cosx=m processes solution then range of the range of values of m is given by?

Answer 1

-(2)^(1/2)<m<2^(1/2)
since 2^(1/2)*sin(x+(pie/4))=m
& -1<sin y<1

Answer 2

where do all you guys learn to spell "pi" as "pie"?

Does no one ever teach about the Greek alphabet any more?
