Remember you can put functions within a function!
# General Functions:
- solve(equation, variable)
- keyboard → math 1 → solve
- Will solve for the variable from the equation
- Adding (solve() | x = y) means x will be replaced with y
- i.e: solve given that x = y
- solve(equation, variable)
# Vector Functions
- Finding unit vector → e.g: ${\hat{a}}$ if $a =$ $[{{x}\atop{y}}]$
- unitV($[{{x}\atop{y}}]$)
- action → vector → unitV
- unitV($[{{x}\atop{y}}]$)
- Finding magnitude of $a + b$ → e.g: |$[{{i}\atop{j}}]$ + $[{{x}\atop{y}}]$|
- norm($[{{i\\ + \\ x}\atop{j\\ + \\ y}}]$)
- action → vector → norm
- norm($[{{i\\ + \\ x}\atop{j\\ + \\ y}}]$)
- Finding angle between two vectors
- angle($[{{i}\atop{j}}]$, $[{{x}\atop{y}}]$)
- separate vectors with a comma
- action → vector → angle
- angle($[{{i}\atop{j}}]$, $[{{x}\atop{y}}]$)
- Solving dot product
- dotP($[{{i}\atop{j}}]$, $[{{x}\atop{y}}]$)
- action → vector → dotP
- dotP($[{{i}\atop{j}}]$, $[{{x}\atop{y}}]$)
- Finding unit vector → e.g: ${\hat{a}}$ if $a =$ $[{{x}\atop{y}}]$
# Other Important Stuff
- The factorial (!) button is found under advanced tab in the second page of the keyboard
- If you need to write something as ${+ \atop -}{\sqrt{x}}$, write out the equation twice
- One for positive surd x and one for negative surd x
