The problem is a trig problem(dealing with Sine,Cosine, and Tangent)
A train is traveling up a slight grade with an angle of inclination of only 2 degree. After traveling one mile what is the vertical change in feet?

-
set up a right triangle. 1 mile is the hypotenuse.
you know that sin is opposite over hypotenuse
sin(2 degrees) = height / 1
height = sin (2 degrees)
note* be sure your calculator is in degree mode and not radian
