Question

How do you find the H-Shift.
My problem is y=5 sin(3x-pi/2).

Answer 1

Do you mean horizontal shift?

Look at this:

(3x-PI/2)= 3(x-PI/6)

see the PI/6 term?

Answer 2

Do you mean where does the function cross the x axis first after x = 0?
If so it is when
3x-pi/2 = 0
or
x = pi/6

Answer 3

yes I meant horizontal shift. so PI/6 is the answer?

Answer 4

Jennifer, graph it starting at x = 0 and go to x = pi/3
see where it crosses the axis

Answer 5

then what's the ending point?

Answer 6

It is a sine function. It goes on and on forever. The shift is just how much it is offset from the origin by being sin(3x-pi/2) instead of being sin(3x)

Answer 7

never mind. I get it.

Answer 8

atta go :)
