![\bf \textit{now, with that template in mind, let's see} \\\\\\ y=3cos[4(\theta +45)]-4\implies y=\stackrel{A}{3}cos(\stackrel{B}{4}\theta \stackrel{C}{+180})\stackrel{D}{-4} \\\\\\ \stackrel{phase~shift}{horizontal~shift}\qquad \cfrac{C}{B}\implies \cfrac{180}{4}\implies 45 \\\\\\ period\qquad \cfrac{2\pi }{B}\implies \cfrac{2\pi }{4}\implies \cfrac{\pi }{2}\implies 90^o](/tpl/images/0161/7392/046d6.png)
