Cos 45 = 1/ √ 2
sec 30 = 2/√3
cosec 30 = 2.
=1/√2 / 2/√3+2
=1/√2/2+2√3/√3
=1/√2*√3/2+2√3
=√3/√2(2+2√3)
=√3/2√2+2√6  (1)
=√3 (2√62√2)/((2√6)+2√2))(2√62√2)
=2√3(√6√2)/(2√6)²(2√2)²
=2√3(√6√2)/248
=2√3(√6√2)/16
=√18√16/8
=3√2√6/8 (2)

I need to learn this trigonometry from A level.. can anyone help here?
cos(a+b)+cos(ab)/sin(a+b)sin(ab)=cotb ... pls some one should help me with this..thanks in anticipation
f(x)=x/x+2 given g(x)=1+2x/1x show that gf(x)=1+2x/3
sebd me some questions about anything ill solve for yall

how to solve x²=2x+8 factorization?
x=2x+8
x2x=2x+82x
x2x=8
x=8
x/1=8/1
x=8
prove:
if x=8
8=2(8)+8
8=16+8
8=8
(PROVEN)
Manifoldee
×=2x8 minus both sides by 2x
Manifoldee
so, x2x=2x+82x
Manifoldee
then cancel out 2x and 2x, cuz 2x2x is obviously zero
Manifoldee
so it would be like this: x2x=8
Manifoldee
then we all know that beside the variable is a number (1): (1)x2x=8
Manifoldee
so we will going to minus that 12=1
Manifoldee
so it would be x=8
Manifoldee
so next step is to cancel out negative number beside x so we get positive x
Manifoldee
so by doing it you need to divide both side by 1 so it would be like this: (1x/1)=(8/1)
Manifoldee
SO THE ANSWER IS X=8
Manifoldee
so we should prove it
Manifoldee
x=2x+8
x2x=8
x=8
x=8 by mantu from India
mantu
lol i just saw its x²
Manifoldee
x²=2x8
x²2x=8
x²=8
x²=8
square root(x²)=square root(8)
x=sq. root(8)
Manifoldee
I mean x²=2x+8 by factorization method
Kristof
I think x=2 or x=4
Kristof
x= 2x+8
×=82x
 2x + x = 8
 x = 8 both sides divided  1
×/1 = 8/1
× =  8 //// from somalia
