Question

Maximum value of y=sinA+2cosA

Answer 1

Answer:

Maximum value = √(1² + 2²)

= √(1+4) =√5

Step-by-step explanation:

If anything is in

aSinx + bCosx

Or , aSinx - bCosx

Or , aCosx - bSinx

Or , - aCosx - bSinx

In everyone of them

Formula of maximum value is

√(a²+b²)

Mimimum value is -√(a²+b²)
