Differentiate to get the maximum value.Ok..uh, in a bit stuck.
1. Determine the greatest possible value of
Well i know that the greatest value of a sin function is 1...so overall this would give - 3.
The min value of a sin function is -1...so overall this gives the value 3..
However the second part of the question is
b.) determine the value of x/
The answer is 9....i get -27...what am i doing wrong :S?
I know that if the sin function is to be -1 then
and re-arranging gives x = -27.
After converting cosec x into 1/sinx and multiplying through... i get this but now im stuck lol.
Any help would be greatly appreciated. Thank you!
