Question 898439: (1) What are the zeros of y=secx?
(2) Find the maximum for y=3cos2x
(3) A helicopter is hovering 1000 feet above the surface of a lake. the helicopter is observed by the crew of a boat as they look upwards at an angle of 25 degrees. twenty seconds later, the crew has a look at an angle of 70 degrees to see the helicopter. How fast was the boat travelling?

(1) What are the zeros of y=sec(x)?
-----
If x = 0, y = 1
If y = 0, x is undefined
------
(2) Find the maximum for y=3cos2x
If x = 0, y = 3*1 = 3
----------------------------
