I tried finding the average value of the function and came out with the answer .5554 sq. units. Is this correct?
3 things fundamentally wrong with that.
1) The minimum value of sin(x) on is in the neighborhood of 0.7 This definitely suggests that the AVERAGE value is unlikely to be less than 0.7.
2) Square Units? Why would it be "square"? The sine function does not produce square units.
3) You showed NONE of your work so now no one can help you fix whatever it was that caused you to wander off.
A) What is the total area under the curve?
B) If it were a rectangle with that width and that area, how tall would it be?
Do you remember the special angles. Look at my last post again. And check this out
