2011年8月6日 · cot(pi/2) = 1/tan(pi/2) = 1/undefined =/= 0 I don't see how the two are equal, and you I think I may be getting some things mixed up as I haven't dealt with basic trig in several years lolz Aug 4, 2011

2012年4月13日 · Homework Statement i wanted to know ,why is the range of cot-1(x) (0,π), unlike tan-1(x) which has its range (-π/2,π/2). because for sin and cosec inverse range is same, for cos and sec inverse range is same. Homework Equations The Attempt at a Solution

2009年7月20日 · If arctan(x) = tan(x)^-1 and since tan(x) = sin(x)/cos(x) is not arctan(x) = cot(x). I know something's not right here but what is it? Thanks.

2012年7月20日 · No, cot and arctan are completely different functions JeeebeZ. Why don't you post your working. It looks like you may be confusing inverse functions with reciprocals, which is very wrong, but not all that an uncommon mistake for students who are just starting out with manipulating functions.

2007年12月17日 · Homework Statement cot x= 0 How do I figure this out? I can't remember how to do it. It makes sense the answer would be zero. But I got my test back and the answer was 3pi/2 +2pik. This answer doesn't make sense. Homework Equations This is what I remember. cot^-1=x I don't...

2011年8月12日 · If your calculator doesn't have a cot function, use the tan function followed by the 1/x function. [you best take the tan 63 to start with and write that answer down for reference.

2016年3月12日 · Homework Statement Show that the scatter angles of the photon (θ) and electron (Φ) in the Compton effect are related by the relation: ##cot (θ/2 )=(1+\\frac{hf}{mοC^2}) tan(Φ) ## Where f is the frequency of incident photon 2. The attempt at a solution I wrote down the equations of conservation...

2015年4月9日 · Homework Statement Show that sin(2θ) / (1 + cos(2θ) = tan(θ) - I've completed this part Hence find the value of cot(π/8) in the form a + b√(2), where a, b...

2012年6月2日 · I have researched this area a little bit and now I am a little worried because three different websites have gave me three different answers. Some functions matched, but others didn't. My general consensus is inverse Sin= 1 and 4 quad inverse Cos= 1 and 2 quad inverse tan= 1 and 4 quad...
