f(x)=sqrt (16-x^4)/ sinx

This is to evaluate a limit, but I don't know if I can simplify the above equation. Because I tried to get rid of the radical in the numerator but I ended up with a radical in the denominator. >< Help

**Neee**, Saturday, August 14, 2010 at 9:52amWhere is f(x)=(sqrt(16-4^4))/sinx continuous? Evaluate lim x-> pi/2 f(x)

as x>PI/2

Then limit is easy...

Lim = sqrt(16-(pi/2)^4)/1

I dont see the problem.

Now, where is it continous?

when 16-x^4 goes negative, there is a problem with a sqrt of a negative number, so when x=2, there is a disconituity as the f(x)=0 .
