this is an expression. i meant that it was not something like 2pi/3 or something that CAN be written in this form. but this was an expression which must be simplified as u said.
well, lets pray that we get 9A*s inshallah
(although i can see B in english)

Are u sure? Wait we had to find the gradient if the tangent first, and then the gradient of the normal. I found the y coordinate then and then formed the equation of the normal, plugged in x=0 and I got [3pi - (something)] :S did I do something wrong? There weren't any calculation errors cause I checked again

I'm giving you the usual pattern of things in the papers. What came today won't come on Paper 2 most probably.

oh ok thanks.

 

[Nouman1997]

I got (pi minus 40) upon someting

 

[Snowysangel]

My gradient of the normal was really weird. It was -(1/9) or something

It was -1/6

Yeah, P was (0,pi/8-5), i.e, (0,(pi-40)/5)

What were the permutation answers? Anyone remember them?

360
60
36

 

[UFO_far_planet]

360
60
36

phew. got them right

and did u get 2 values each for the trig equations?

Yes.
90, 270.
1.31, 2.88

in rv, we have to write bearing as 9.1 degrees or 009? Saad Mughal

 

[Ishrar Afrida]

y-coordinate of D = 8


How come BC is the perpendicular bisector of AD? :/

Find detovatove function to find tangent gradient, to find gradient of notmal, to find c, which was y coordinate of p.

009.1 deg
Three digits and one decimals place.

Better write 009.1 degrees. 3-digits and 1 d.p.

What is ' detovatove function'?

009.1.

 

[Saad Mughal]

The 90 degree angle.

Derivative XDDD
