anyone explain sin cos for paper 1

sin x = cos (90 - x) (check on calculator)
sin x = sin (180- x)
cos x = -cos (180 - x)

 

[syed1995]

sin x = cos (90 - x) (check on calculator)
sin x = sin (180- x)
cos x = -cos (180 - x)

I have them and the quadrants memorized .. <-- Addmaths.

@::A^
(12)^0.5 ko yun b likh saktay hai (2 x 2 x 3) ^0.5 thus 2 ka ek pair hai to take 2 out ull get 2(3)^0.5
3^3/2 = 27^0.5 = (3 x 3 x 3)^0.5 yaha b 3 ka ek pair ban raha hai to take 3 out it will become 3(3)^0.5

now 3^0.5 are cancelled leaving 2/3

tumhe ye tab he samajh aega if you know how to take out numbers from square roots

4/3 is ryt ms have their mistakes

 

[syed1995]

10 – 3(2x – 1) = 3x + 1 .
10 - 6x + 3 = 3x +1
13 - 6x = 3x +1
12 = 9x
x = 4/3

 

[moni]

24 c of that paper

 

[MustafaMotani]

pakistani and indian are rivals know great to see them collaborating nd sri lanka is small compared to ur country

size of the country has nothing to do wid it... i m just saying dat mostly viewers are from pakistani and india
