3 Answers. I know ways to solve this by expanding sin(5x) but I'm wondering if the method I'm attempting below is correct and how to proceed with it: \(\displaystyle \displaystyle \sin 5x = -sin x \implies \sin 5x = \sin {-x}\) <--- hmmmm, I never heard about that identity
Find the value of ∫(sin 5x/sin x) dx for x ∈ [0,π/2]. sin5x. The first angle is found by converting the cosine function into the negative of the sine function by subtracting 90^@: -sin(x - 60^@) = sin(5x + 12^@) Use the identity -sin(a) = sin(-a) sin(-x + 60^@) = sin(5x + 12^@) Equate the arguments: -x + 60^@ = 5x + 12^@ 6x = 48^@ x = 8^@ Because 5x - -x = 6x, this
So $(\cos x,\sin x)+(\cos 5x,\sin5x)$ lies even with the $(\cos3x,\sin3x)$ term and the sum of all three vectors is parallel to $(\cos3x,\sin3x)$, as required.0005 \sin(5x).
