Question

Use the intermediate value theorem to solve.. (Problem typed in the comments) please help me :(

Answer 1

I dont understand this because it doesnt match my notes and Im lost.

Answer 2

compute
\[h(0)\] and also \[h(\frac{\pi}{4})\]
one will be positive, the other negative
since this function is continuous on that interval, it cannot skip values, so if it is positive somewhere and negative somewhere it has to take on all values in between, one of which is \(0\)

Answer 3

so h(0)= 1 and h(pi/4) = -2. So then the zero would be (0,1)?

Answer 4

Im confused on how to put the answer then
