Suppose P is a point on the unit circle in Quadrant IV. Find the missing coordinate of the point.
The terminal point determined by t is the point on the unit circle. Find the terminal point for each of the following:
a) t
b) c2+3
a) Find the missing coordinate of the terminal point P if we know that.
b) Find the value for tangent c. If t has the terminal point in part a and 0<t<2, what is the reference number of t?
Find the quadrant in which the terminal point determined by t lies: tangent 0 and sine <0.
Suppose the temperature, T, on a particular planet oscillates between -60°F and 200°F every 37 days. Write a possible formula for T as a function of days. Assume the maximum temperature is reached when t=0.
Write the equation for a sine function with a maximum at 7 and a minimum at (1).
Electric fans A and B have a radius of lft and, when switched on, rotate counterclockwise at the rate of 100 revolutions per minute. Starting with the position shown in the figure, the fans are simultaneously switched on.
a) For each fan, find an equation that gives the height of the red dot above the horizontal line shown t minutes after the fans are switched on.
b) Are the fans rotating in phase? Through what angle should fan A be rotated counterclockwise in order for the two fans to rotate in phase?
