whitecorp sir---u r my only saviour

 

[parthrocks]

hello can anyone plz help me with this:-
just question number 10 plzzz !

 

[shanky631]

That is correct, I teach A level H2 maths. Have a good day too. Peace.

Thank u sir, u are great. I am finally confident in vectors because of ur explanation. Can u plz also help me in sketching argand diagrams

 

[pennies]

can someone please solve part (b)? whitecorp i really need help




also can u do part (iii) of this question? and draw the argand diagram? please?

For Q10, I will require the answers from (i) and (ii) (a).

Here are the solutions for Q7 (complex numbers Argand Diagram):



Hope this helps. Peace.

How do u question 10 (i)???

Here are the workings:



Hope this helps. Peace.

Okay guys heres a real simple part in vectors that almost always comes up!

How do you go about finding a point on the line???

Ya you are right!!!i think first we need to solve them simulatenously by rither putting x,y or z as 0 and then you get the value for the normal and then
r=a +t(p) and i think a point will be given ?

YOu can get the value for the normal by using the normal/vector cross product rule and that will give you the equation for the line, but as for the point, we are not give it thus we need to use a method to obtain the point
Here are 3 methods given by cambridge, yet i dont understand any of them, lol

Bro, u can take the value of one component as 0 and then solve the two plane equations simultaneously to get the points.

okay dude plz quickly show us the working then
