Web\tan (x) = \dfrac {1} {\cot (x)} = \dfrac {\sin (x)} {\cos (x)} tan(x) = cot(x)1 = cos(x)sin(x) Notice how a "co- (something)" trig ratio is always the reciprocal of some "non-co" ratio. …
Web5 years ago. Sal was trying to prove that the limit of sin x/x as x approaches zero. To prove this, we'd need to consider values of x approaching 0 from both the positive and the negative side. So, for the sake of simplicity, he cares about the values of x approaching 0 in the interval (-pi/2, pi/2), which approach 0 from both the negative (-pi ...
