Question

how do you shift a trig function horizontally and vertically?

Answer 1

same way you do any function; modify the x or y as needed

Answer 2

thats what i thought i wanted to be sure.

Answer 3

are u good with cosine functions?

Answer 4

i can only do secant functions, everything else is completely different :/

Answer 5

what about a cosine function do we need to be good with?

Answer 6

i need help on how to solve them

Answer 7

maybe you should give an example of something that you need help solving ... otherwise this is going to be rather vague

Answer 8

mine is an amplitude of 7 a period of pi/6 and a vertical shift of down 2

Answer 9

and what have you tried to work up so far? what are yourb attempts?

Answer 10

... dunno how that b got stuck in there

Answer 11

well actually my first question is.. is it graphed or rather can you graph to solve?

Answer 12

graphing is never a good option, sketching is useful at times but if its an equation you need then that simply wont work

Answer 13

can you tell me what an amplitude and a vertical shift does to the parent function?

Answer 14

well i know that a sketch of this type of problem is like wavelength in science its a wave. with an amplitude shift the waves will either get farther apart or closer together. and a verticle shift makes the wavelentgth shorter or longer

Answer 15

for amplitude it was farther or closer from left to right

Answer 16

and the verticle shift could be moving the whole wave down aswell

Answer 17

or up

Answer 18

lets clean that up some :)

amplitude measures how tall the graph is from the centerline.
