The differentiation of sin x plus cosx is cos (x)-sin(x).
sin7x-sin6x+sin5x
d/dx[sin(4x)] = sin(4x) ======
Sin 15 + cos 105 = -1.9045
The proof that sin2A plus sin2B plus sin2c equals 4sinAsinBsinC lies in the fact that (sin 2A + sin 2B + sin 2C) = 4 sinA.sinB.sinC.
The differentiation of sin x plus cosx is cos (x)-sin(x).
sin7x-sin6x+sin5x
differentiation of sin x + cos x.
The derivative is 1/(1 + cosx)
d/dx[sin(4x)] = sin(4x) ======
Sin 15 + cos 105 = -1.9045
The proof that sin2A plus sin2B plus sin2c equals 4sinAsinBsinC lies in the fact that (sin 2A + sin 2B + sin 2C) = 4 sinA.sinB.sinC.

[sin - cos + 1]/[sin + cos - 1] = [sin + 1]/cosiff [sin - cos + 1]*cos = [sin + 1]*[sin + cos - 1]iff sin*cos - cos^2 + cos = sin^2 + sin*cos - sin + sin + cos - 1iff -cos^2 = sin^2 - 11 = sin^2 + cos^2, which is true,
No. sin(0) = 0 So cos(0)*sin(0) = 0 so the left hand side = 1
The result is variant, therefore uncertain. The only sure thing is that sin(x)2 + cos(x)2 = 1.
