revirth / Finding Component.py

Created January 24, 2016 14:40

When I study Vectors on KahnAcademy site, need to make a function to calculate to find a component from 2 vectors

	# https://www.khanacademy.org/math/linear-algebra/vectors_and_spaces/vectors/e/adding-vectors-in-magnitude-and-direction-form

	def findComponent(v,vR,w,wR):
	l = vmath.cos(math.radians(vR))+wmath.cos(math.radians(wR))
	r = vmath.sin(math.radians(vR))+wmath.sin(math.radians(wR))
	return (l,r)
