SPECIALIS MATHEMATICS - VECTORS ON TI 89 TITANIUM. Enter vectors and store using the column vector notation: Vectors MATH Matrix Vector ops menu Find the angle between vectors a = 2i + 8j + k b = 8i - 4j + 13k To find a unit vector in the direction of a. Go to Maths, 4: Matrix, L: Vector ops, 1: unitV( The magnitude of a vector Maths, 4: Matrix, H Norms 1:norm( Alternatively find norm( in the Catalog. To find the dot product, select Maths, 4: Matrix, L: Vector ops, 3: dotP( Alternatively use your Vectors program to find the angle, magnitudes, dot product etc. VECTOR RESOLUTES: Given that u = 6 i + 2 j − 6k and v = 6 i − 2 j + 6k find: a. the vector resolutes of v in the direction parallel and perpendicular to u . Enter both vectors and store as u and v. v parallel = (v ⋅ uˆ )uˆ v perpendicular = v − v parallel Find û : ©Bozenna Graham 2009. 1 [email protected] Find the scalar product of v ⋅ uˆ : Now find (v ⋅ uˆ )uˆ : And finally v perpendicular = v − v parallel : b. the shortest distance form point P to the line parallel to v . The shortest distance d is equal to the length of the perpendicular resolute of u onto v. . Parallel component: Length of the perpendicular component: Perpendicular component: As a decimal: ©Bozenna Graham 2009. 2 [email protected]
