, sin(-θ) = -sin θ


cos(-θ) = cos θ


tan(-θ) = -tan θ


sin(A + B) = sinAcosB + sinBcosA


sin(A - B) = sinAcosB - sinBcosA


cos(A + B) = cosAcosB - sinAsinB


cos(A - B) = cosAcosB + sinAsinB


sin 2θ = 2sinθcosθ


cos 2θ = cos² θ - sin² θ
= 2cos² θ - 1
= 1 - 2sin² θ


tan θ = sin θ / cos θ
= 1 / cot θ


cot θ = cos θ / sin θ
= 1 / tan θ


sec θ = 1 / cos θ


csc θ = 1 / sin θ


cos² θ = ()(1 + cos 2θ)


sin² θ = ()(1 - cos 2θ)


d/dx (x^n) = nx^(n - 1)


d/dx (fg) = fg' + gf'


d/dx (f / g) = (gf' - fg') / g^2


d/dx f(g(x)) = f'(g(x))g'(x)


d/dx (sin x) = cos x


d/dx (cos x) = -sin x


d/dx (tan x) = sec² x
