Practice problem
If tan(x)=sin(x)cos(x)\tan(x) = \frac{\sin(x)}{\cos(x)}tan(x)=cos(x)sin(x), then what happens when cos(x)=0\cos(x) = 0cos(x)=0?
tan(x)=0\tan(x) = 0tan(x)=0
tan(x)=∞\tan(x) = \inftytan(x)=∞
tan(x)=−∞\tan(x) = -\inftytan(x)=−∞
tan(x)=∞\tan(x) = \inftytan(x)=∞ or −∞-\infty−∞
tan(x)\tan(x)tan(x) is undefined
Type a concept, like “slope” or “photosynthesis”.
