Homework Statement
A plane is approaching an observer from an altitude of 5 mi at a dx/dt of 600 mi/h. Find the d(theta)/dt when theta is 30 degrees, 60 degrees, and 75 degrees.
Homework Equations
tan(theta) = x/y
5csc(theta) = r
The Attempt at a Solution
For my d(theta)/dt I had the formula of 3000/(5csc(theta))^2
The answers I had were wrong according to the text.
Please help.
