This app does simple calculations of 2 vectors anddisplay them in a 3D view.These calculations include finding :------------------------------the unit vector of a single vector (display in graph),the length of a single vector,the slope of a single vector,the addition of two vectors,the subtraction of two vectors,the dot product of two vectors,the cross product of two vectors (display in graph),the angle between two vectors,whether the two vectors are parallel or perpendicular to each other,the projection of one vector onto the other vector,the length of the projected vector,the area of the parallelogram formed by the two vectors (display in graph)Please refer to the screenshots below for details.! V2.2 Important notes: PLEASE READ THIS !Tap TWICE on the (output screen or spaces) to exit after finish inputting the vector components. It will also automatically fill out the empty fields with zeros.Tap 3 times (normal taps, even slow taps are fine) to exit the graph.other updates:i) vector input - no more fixed decimal pointii) a simple calculator is added for scalar inputa) can perform sin or cos on the scalarb) individual vector component can be multiplied or divided by the scalariii) negative sign bug is fixed.Please go to see the tutorial pics at my website if you have any problem on doing the sin or cos combo calculations.Thank you for your support.Cheers. ^.^Y
