Write a user dened matlab function that determines the unit vector and the direction for the line that connects two point (a and b) in space. for the function name and arguments, use n = unitvect(a, b). the input to the function are two vectors a and b, each with cartesian coordinates of the corresponding point. the output is a vector with the components of the vector in the direction from a to b. if points a and b have 2 coordinate each (they are in the x-y plane), then n is a two element vector. if points a and b have three coordinates each (general points in space), then n is a three-dimensional vector. use the function to determine the following unit vectors: (a) in the direction from point (1.2, 3.5) to point (12, 15) (b) in the direction from point (-10, -4, 2.5) to point (-13, 6, -5)

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
