I thought my nightmares were alive when Chapter 4 lessons started. Radian (which is not my fav topic) just had to come back to hunt me in colllege. haizzz... Maybe it will not too bad this time..
Like always... it started off easy. We learnt the basic of the basics like converting (my fav) degrees to (my LEAST fav) radian measures. It was more of a revision but a MUCH NEEDED wan.. :)
Hence, a few examples
Lets just say you want to convert an angle that is in degree to its radian form, a simple formula will be of MAJOR help:
π/180 x (degrees) = radians
In the same way, if you would rather look at your angles in degree form, you will just have to rearrange the formula a 'lil to get:
180/π x (radians) = degrees
Therefore, after this, i think i will not be facing any huge problem converting my radian into degress or vice versa..
OF COURSE, the lesson doesn't stop there.. :)
We were introduced to something relatively new.. well it was new in my case... it was something called ANGULAR VELOCITY
i am sure the word 'VELOCITY' rings a bell.. but you see if velocity is used by itself, it can only be utilised after the distance travelled as been calculated: Which is pretty sad if u want to calculate the velocity for an object that is rotating or moving in a circular motion. But no worries!! There is always a formula to the RESCUE!!! ;)
