what is the period? y=5sin2x

OpenStudy (anonymous):

do we have to find the derivative?

OpenStudy (amistre64):

since x is going twice as fast; the period is quicker

OpenStudy (amistre64):

normal sin has a period of 2pi; so this is a period of pi

OpenStudy (anonymous):

wht does period mean?

OpenStudy (amistre64):

a period is one cycle

|dw:1327676709150:dw|twice as fast

OpenStudy (amistre64):

not to scale :)

OpenStudy (anonymous):

so will my answer be twice as fast

OpenStudy (mertsj):

The coefficient 2=2pi/period so period = 2pi/2=pi
