Hi. I need help to find the:

-Amplitude

-Period

-Vertical Shift

-Horizontal Shift

1) y= 2sin(4x+pi)+3

2) y= -3cos((x/2)+2pi)-5

Any help would be greatly appreciated.

a few things to remember

Amplitude is never negative (it's an absolute value)

the period of a sin and cos is 2pi / B. Same for sec and csc,

vertical shift is the number that's outside (you got that right in these cases)

horizontal shift is -C/B if I'm not mistaken. - Nov 5th 2009, 09:30 PMpacman
here is the graph of the two trigonometric equations, try to figure out the answer by inspection . . .
