Question 6.3.3 Could you please explain to me why you were still left with a half and cos 2x when you divided cos2x with 2 ❤️I don’t understand where the half came from and the 2
@mathswithgustin2 ай бұрын
The 2 is from the tan x, the reason we divided everything by to so that we go back to the equations of the given functions... the half is from when u divided 1 by 2 which gives half... u would do the same if u have 2x squared then solving for X u would divide by 2 to get X squared...

Sir , I have been rewinding the video from 5000 I don't really get how you got 1.5 as years , like why are you saying you've got 0.5 and 1 like I'm kinda confused, could you help please . I'm talking about question 5.2.2
@mathswithgustin2 ай бұрын
Sino, think about in this way 12 months= 1year so wat is half a year? Will 0.5, so it is 1.5.... lets say e.g lets say I have a brother who's 2years and a half older than me, therefore it will 2+0.5= 2.5 years...

Sir , in 1.3.2 you said that we take the values of x and y where by they are not equal zero , then you take the value of x where it is equal 4 which is fine and you take the value of y where by it is equal -2 , so my question is why don't you take the value of y when equal 2?
@mathswithgustin2 ай бұрын
Good question, it is because when y=2 , X=0 so u can't use x=0, it give us an error. We can't divide by 0
