Question

find the where the function increases and deceases f(x)=tanx

Answer 1

hi pretty, will u gimme a medal for this?

Answer 2

f'(x)<0, graph is decreasing , f'(x)=0, it is not decereasing or increaasing, f'(x)>0, it is increasing

Answer 3

BAM goes the answer

Answer 4

are there # because
Tangent Function:
One cycle occurs between -pi/2 and pi/2 .
There are vertical asymptotes at each end of the cycle. The asymptote that occurs at pi/2repeats every Pi units.
period: pi
amplitude: none, graphs go on forever in vertical directions.

Answer 5

cohesive, that was beautiful description

Answer 6

Thanks

Answer 7

hmm that sdeont really answer my question, im suppose to find the largest intervals on which f is increasing and decreasing between -pi/2<x<pi/2

Answer 8

for starters, f nvr decreases.

Answer 9

for tanx

Answer 10

please explain :)

Answer 11

tan x only increases back to my example
•intervals of increase/decrease: over one period and from -pi/2 to pi/2, tan (x) is increasing

Answer 12

@JoannaBlackwelder can you help explain plz

Answer 13

Look at the graph. From left to right, it always rises. Thus it is increasing everywhere.
