[SOLVED] Problem with Extremum in Function App
Hello all,
I was plotting two simple cos and sin graphs when I came across a strange error. When I was finding Extremum from the Grapher in the Function App, it displayed the y coordinate as 0! The correct value should be 0.5. I have linked photos so you can see what I did.

That's a weird one.

Simplifying the problem: plotting A*SIN(X) or A*COS(X) where -1<A<1 exhibits the same behavior for local maxima where X>0.

Haha, that's a very succinct way to put it.
