does anyone of you remember paper 3, the differential equation question, part 3, where we were asked to find y when x=25?did you get around 10900?

Was it from variant 2 ?

I got paper 12 answers as well.

So you upload P3 solutions like I added of P1

I solved the whole paper, do it na.
Okay, I will do the rest.

How to solve trigonometrical equations within the range of -180< x <180? Is there any simple way to solve such equations easily?
Here are some examples I want to see how we can solve them
(a) (3 square root 3) sin x = cos x
(b) sin square x = 0.5

dude u already asked ths n i already replied lol

ok lemme tell u again
ive no calculator now so i wont be givin u the values..only steps though

(a) make in terms of tan
constants on one side and identity (tan) on one side
tan inverse then u get key angle
to make answer in range add or minus 360

same goes for (b) add or minus 360 to answers u get whn solving quadrants.

btw no one asked abt p3 y shld i upload?

Isn't tan add/minus 180?

Also for B I would rather square root the equation, giving sinx = sqrtroot 0.5. After finding x, don't forget that x can have two kinds values: x+360k and (180-x) + 360k.....

i said AFTER SOLVING QUADRANTS THEN add 360 or minus to make in range

It's TimBluesWin btw... Are there anyone that asked for p3 solutions? :O

Its + or -
