There is a search option, just below where u check ur alerts, just type there paper 3 chemistry practical tips. or any thing u wanna seaarch.

Thanks for the luck, u too good luck. Have u gone through notes/tips uploaded for paper 3 of chemistry here?

I got it. Maybe u have done some mistake, it will be sin(x)/cos(x) = (-2sqrt(3) + sqrt(2))/(2-sqrt(2)) now u will get it when u add 180 degress to ur x to make it in the domain.

what is answer?

why wrong?

yes.

Use addittion formulas, and solve it.

Oh i didnt get this before :/ idk why. (1 + i) (- 3i) = 3 - 3i draw the circle with origin at u and radius being absolute of u. basically that is asking us to drow locus of |z - (-2/5 + 11/5i)| = sqrt(5)

Yes. It doesnt.

Just make argand digram like any simple graph thats it, and plot the points as given. If u are not asking for this, i am not getting what are u asking for.

Kp = 1^2/(28)^2

Welcome to XPC.

ii) Draw haf line with centre at u at angle of pi/4 draw perpendicular from line to origin, and find its distance that is least value of |Z| iii) Draw circle with centre (1 + i)u with radius 1. and the distance from origin to the maximum distance of circle is greatest value of |Z|

Remaining question : http://justpastpapers.com/wp-content/uploads/2016/05/scan0103-1.jpg : paper 32 paper 33 : Draw argand diagram with point OABC shown clearly, prove two oposite sides are equal and show its gradient are same it is parallelogram. angle can be calculated using cosin rule.
