yeah... not sure if im supposed to do it in degrees or radians.
tan 90 -tan theta / tan 90 tan theta
-2 -tan theta/ -2tan theta

 

[Rutzaba]

its made up from a triangle actually
using the Sin(thetha)= O/H .......
can you do part iii using it?

its too lengthy

 

[Rutzaba]

2p +root of 1- p^2 whole divided by 2 root of 1- p^2

 

[ZaqZainab]

its too lengthy

so what am i suppose to do then?

 

[Rutzaba]

O shit i used the wrong formula
the ryt formla is
tana - tanb/1+tanatanb

how do you use it

 

[Rutzaba]

how do you use it

dnt wrry its not in ur course

You both are awesome, go to www.twiddla.com

 

[Rutzaba]

how do you use it

in tan(90-theta) 90 is a and theta is b
but tan 90 is infinity so dnt get confused and simply memorise ur set of formulas

dnt wrry its not in ur course

But asked in our paper

needs Second part only . when meet x-axis what happens , just tell me this
I got first one as 12x+6y-6z=48 , and second one is ( -2 , 7 , -5 )
Tell me what happens when parallel to x-axis only .
For complex no. , i got step except how they used y=x f
