WebFeb 13, 2024 · For some angles $\alpha,\beta$, what is $\sin\alpha+\sin\beta$?What about $\cos\alpha + \cos\beta$?. My line of thought was to designate $\theta=\alpha+\beta$, for $0\le\alpha\le 2\pi$.By much experimentation, and scratching my head when I saw that $\sin$ needed a horizontal-shift term that depended on $\theta$ while $\cos$ didn’t, I … WebClick here👆to get an answer to your question ️ The general solution of the equation sin^2 theta = sin^2 alpha is.
