Was it from variant 2 ?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?
How you do that in other site? -_-
sorry do what?How you do that in other site? -_-
just type the text double click it then click on link buttonHow you do that in other site? -_-
already given p3 kiddoI have solved full paper 3 of oct nov. RoOkaYya G need it?
So you upload P3 solutions like I added of P1already given p3 kiddo
n ive solved em all too ^_^
yeah ill upload the ones tht guy asked only. its too much to type anyway -_- 4 questionsSo you upload P3 solutions like I added of P1
I solved the whole paper, do it na.yeah ill upload the ones tht guy asked only. its too much to type anyway -_- 4 questions
oki xDI solved the whole paper, do it na.
Okay, I will do the rest.
dude u already asked ths n i already replied lolHow 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
btw no one asked abt p3 y shld i upload?I solved the whole paper, do it na.
Okay, I will do the rest.
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.
TimsBlue need itbtw no one asked abt p3 y shld i upload?
TimsBlue need itbtw no one asked abt p3 y shld i upload?
i said AFTER SOLVING QUADRANTS THEN add 360 or minus to make in rangeIsn'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.....
