According to de Moivre's formula,
cos3x + isin3x = (cosx + isinx)3 = cos3x + 3cos2x*isinx + 3cosx*i2sin2x + i3sin3x
Comparing the imaginary parts,
isin3x = 3cos2x*isinx + i3sin3x
so that sin3x = 3cos2x*sinx - sin3x
= 3*(1-sin2x)sinx - sin3x
= 3sinx - 4sin3x

There is no formula for a theorem. A theorem is a proposition that has been or needs to be proved using explicit assumptions.
This can't be done with a single exponent, as 325 is not a power of 18. It is however very close, and can be done using two terms with different exponents:182 + 180 = 325So if you were to express it using base 18 notation, it would be "101"
an arithmetic tree an is formula using prime and composite number to express its factors.
You can use Riemann sums. If you can express your shape using a set of points (x_i,y_i), you can express the area as: area = area + y_i * (x(i+1)-x(i-1))

Theater is a way to express yourself by acting. By using your role and charteristics of that character, you can express yourself by using what you know or have experienced about it. You show in your perspective of the role how you would have done it. You express it in your own way.
The expression (\sin(3\alpha)) can be expanded using the triple angle formula for sine, which is (\sin(3\alpha) = 3\sin(\alpha) - 4\sin^3(\alpha)). This formula allows you to express (\sin(3\alpha)) in terms of (\sin(\alpha)).
This is a simple sentence using the words "chemical formula".
