[applepie1996]

yeah and vectors yuck..AS vectors was cool thought but not A2 :S

ha ha I KNOW ! don't even know where to start from :S

 

[Rutzaba]

GUYS I HAVE THE MATHS P1

 

[19islandprincess96]

How do we know the equation of the plane OAB? We need it to find the angle, right? In part ii?

how to solve

 

[Esme]

how to solve

( (1-x)^1/2 ) ( (1+x)^-1/2 )
Use binomial expansion for both of them separately and then multiply them

 

[Esme]

When finding the angle between a plane and an axis ( for example y-axis), do we have to take sinθ or cosθ ?

Rutzaba or anyone ??

applepie1996 could you help me out please ??

 

[Dug]

When finding the angle between a plane and an axis ( for example y-axis), do we have to take sinθ or cosθ ?

Rutzaba or anyone ??

You can use both! But if you use cosΘ, you will have to subtract your answer from 90°.
