An airplane is flying east by northeast (22.5 deg from due east) at a constant speed of 400 km/hr. At the moment when it is 1 km east and 2 km north of a radar station that measures the airplane's position in polar coordinates, (r,theta); find dr/dt and d(theta)/dt.

calc 1?

anonymous · Answer

Vector Calculus. An extension of multvariable calcululs (Calc III) So I guess Calc 4?

anonymous · Answer

just wondering what I have to look forward to. Im in pre-calc but have to go through calc 3 and differential equations.

anonymous · Answer

Calc 3 is kinda boring. But DE is definitely fun.

anonymous · Answer

I imagine that's where most all the theory is behind you and you get to play with real world models and problems

anonymous · Answer

Vector calculus is formally called linear algebra.
