sin(3A) = sin(2A + A) = sin(2A)*cos(A) + cos(2A)*sin(A)= sin(A+A)*cos(A) + cos(A+A)*sin(A)
= 2*sin(A)*cos(A)*cos(A) + {cos^2(A) - sin^2(A)}*sin(A)
= 2*sin(A)*cos^2(A) + sin(a)*cos^2(A) - sin^3(A)
= 3*sin(A)*cos^2(A) - sin^3(A)
Cannot prove that 2 divided by 10 equals 2 because it is not true.
a0=(a-1\a-1)=a\a=1
It is extremely difficult to prove things which are not true.
You can't prove it, because it's usually not true.The only time it's true is when x=0 .
that cannot be proved because it is not necessarily true.
Cannot prove that 2 divided by 10 equals 2 because it is not true.
You can't it equals 2. You can't it equals 2.
No you can not prove that 9 +10 = 21.
No, but there is a way to prove that zero equals one.
Using faulty logic.
a0=(a-1\a-1)=a\a=1
