- Homework Statement
- I am supposed to find the limits of a trig function, which I have managed to do, but I don’t know how to show that the range can be achieved within the given domain.
- Relevant Equations
- y = 2sin(x)
y = 2sin(x)
-1≤ sin(x) ≤ 1
-2 ≤ 2sin(x) ≤ 2
so -2 and 2 are the max/min limits
but the domain is -π < x ≤ π
Do I find the values of x that outputs -2 and 2 and show that they are within the domain ?
