Rsin theta+alpha
Web3cos (theta) + 5sin (theta) = R [cos (alpha)cos (theta) + sin (alpha)sin (theta)] By comparing either side, you can see that Rcos (alpha) = 3 (equation 1) and Rsin (alpha) = 5 (equation 2) Another identy you should know is sin^2 (alpha) + cos^2 (alpha) = 1 Therefore: R^2cos^2 (alpha) + R^2sin^2 (alpha) = 3^2 + 5^2 Factoring out R^2: Web目录：点我 思维导图下载：点我 一、概念 1. 和式极限 ∬Df(x,y)dσlimn→∞∑i1n∑j1nf(ab−ani,cd−cnj)⋅b−an⋅d−cn\iint_Df(x,y)d ...
