a=a1(alpha) + a2(beta) + a3(gamma)
b=b1(alpha) + b2(beta) + b3(gamma)
c=c1(alpha) + c2(beta) + c3(gamma)
How to show that a.(bxc) = λ (alpha) .(beta x gamma) and find out λ?
Three vectors are expressed in terms of other three vectors
in the form of
a=a1α + a2β + a3γ
b=b1α + b2β + b3γ
c=c1α + c2β + c3γ
How to show that a.(bxc) = λ α.(βxγ) and find out λ?
I knew the first part where we carry out dot and product rule for vectors a.(bxc),
but the other...
Sorry, my mistake.:smile:
So if I am looking for direction vector, I just get this (-3π, 2, 1)/(magnitude of this vector (-3π, 2, 1)) where (-3π, 2, 1)=the velocity vector?
By differentiating them with respect to t, I should get the velocity vector (x,y,z) = (3 π cos π t, 2t , 1). Then substitute t = 1, (x,y,z) = (-3π, 2, 1).
This is my velocity vector. So how I get the director of the vector when t=1?
Suppose that an object is moving in a space V, so that its position at time t is
given by r=(x,y,z)= (3sin πt, t^2, 1+t)
How to find the direction of the vector along which the cat is moving
at t = 1?
I have no idea where to find out the direction of the vector along which the object is...
