Question

for the function y= 2+3sinx
find the amplitude and the max value

Answer 1

The amplitude is 3 and the max value is 5.

Do you know why/how?

Answer 2

thats not right according to my solution book

Answer 3

Perhaps your solution book is wrong.

I put this directly into wolfram alpha after you tried to tell me it is wrong.

The starting value is of the function is 2, it osciallates around this number, and the max value is the amplitude (3; the coefficient of the sin(x)) plus the starting value of the function.

Answer 4

oh i see

Answer 5

hmmmm.....don't u study the first derivative to find min & max?

Answer 6

@virtus what does your answer book say?

Answer 7

I think my solution is wrong haha

Answer 8

i think chaise is right

Answer 9

Oh, I guess it depends on the way you interpret min and max.

I assumed it was the max value of y. Perhaps you are right in saying that Angela.
