An airplane whose air speed is 620 km/h is supposed to fly in a straight path 35.0 degree north of east. But a steady 95 km/h wind is blowing from the north. In what direction should the plane head?
Here is what I thought:
direction of the plane
then how do you solve for theta?
is there a better way to do it?
Here's how to solve your equation. But it does suggest there may be a better way to set up the problem to make it easier to solve.
Write your equation as
Use the second of these trig identities
If anyone knows of a good web page describing this method, please let me know. The method is called introducing an auxiliary angle.
