When I don't feel like doing math, I just open this app and take a picture of the problem. This app allowes me to get the answers and add the work later, oh mighty This app, take my offering of 5 stars. I probably would've failed math if it weren't for this app.

Amazing it's very helpful the only problem I have is that it can't do multiple math problems at one with the photo math, it has really helped me understand math problems. Never really had a situation where it couldn't give me an answer. Excellent app for students who wanna solve math independently.

This app give me the ability to check my work and see where I have gone wrong so I can make notes on what I need to study and where I'm struggling. Will solve complex equations, this app is literally so good it helps me how to do math sums that I don't know how to solve but I just to say that the person who made this app has to add ratios in it too Whenever I ask a ratio question they didn't get it so kindly add ratios in it too Thnks.

## How to calculate the Unit Vector?

The normalized vector û of a non-zero vector u is the unit vector in the direction of u, i.e., u ^ = u | u | {\displaystyle \mathbf {\hat {u}} ={\frac {\mathbf {u} }{|\mathbf {u} |}}} where |u| is the norm

## Unit Vector

The unit vector of a vector is found by dividing the vector by its modulus. The modulus of a vector is the magnitude of the vector. It is represented by symbol ‘ ‘(hat or cap)

## Finding the Unit Vector of a Vector

Unit vectors are commonly used to indicate a vector’s direction. The direction of a unit vector is the same as that of the provided vector, but its magnitude is one unit. Formula
