Question

tan A/2+cotA/2 = ?
for what value of x is the function sinxcosx a maximum?

Answer 1

i'm sorry, can you rephrase the question?

Answer 2

uh what will x equal when the function sinxcosx is a maximum?

Answer 3

well max(f(x))=max(sinx cosx)
0<max(f(x))<1 right?

Answer 4

just as a reference, now take the derivative of \(sinx*cosx\)

Answer 5

when does it = 0? that is called a critical point or a cluster point.
