Step by Step Math & Science & Finance using the TiNspire CX
Say you need to find the orthogonal projection of v onto W the subspace of R^3 .
You pull out your TiNspire and launch the Linear Algebra Made Easy app from www.ti-nspire-cx.com and enter as follows:
. 
Now, just lean back and view the steps
until the final answer shows. Sweet!
Say we have to..
Find the angle (Theta) between the two vectors
U= cos(pi/4)i + sin(pi/4)j
V= cos(pi/2)i + sin(pi/2)j
When entering these 2 vectors using option 1 6 in Vector Calculus Made Easy we will not use the i-j notation and instead use vector /matrix notation as shown in this image . The angle is derived using arccos(AB/|A|*|B|) and given in radian format.
Note: We know that the vectors differ by an angle of pi/2-pi/4=pi/4 or .785 , which also equals 45 degrees.
