This is a glorious channel!

After 0:38: The argument of a sinusoidal function is ALWAYS in radians or degrees! It's NOT dimensionless!!!

[@toxin_d]

Radians is actually a dimensionless quantity.

It's not that bad if u understand how circles work

[@SlovenskiVuk]

If angular speed and frequency confuses you here's short explanation: angular speed is how much angle you pass(how many circles you pass) through one second. Frequency is how many cycles you pass through a second. So if cycle is a circle(2pi) then angular speed is 2pi * f. If frequency is 2 cycles per second, angular speed is 2*2pi/sec(2 circles per second)

Hi I like your video

[@Ahmed.r.a]

Can anyone tell me what's the name of the device he is using for writing on screen? any tips will be appreciated. =========================================================================================

[@khanacademy]

Adobe Sketchbook, Wacom Bamboo tablet, and Camtasia for video and audio capture. Any similar hardware/software works, too.

[@Ahmed.r.a]

+Khan Academy yes I knew its a Wacom tablet, but there are too many types and prices of Wacom tablets. Please suggest me the best for writing on screen i don't interest in drawing. Im a teacher too from Iraq, and I wish to use these technologies in the teaching just like you. Thanks for the best channel in KZbin.
