1. The vertical position, y, in centimeters, of a point on the rim of the wheel of a stationary exercise bicycle after time, t, in seconds, can be modeled by the equation y = 40sin720t + 50.
a) What is the lowest vertical position that the point reaches?

anonymous · Answer

did you find the smallest value of sin(stuff) ?

anonymous · Answer

isnt it y = -1

anonymous · Answer

sin(a t) has ranges from -1 to 1

40 sin(at ) has ranges from -40 to 40

add 50 to above

                                       10   to      90

so 10

anonymous · Answer

right, sin720t becomes -1

anonymous · Answer

is there any other way to do it

anonymous · Answer

the steps you guys showed works 
i just wanna know if there is more than one way to do it
