Best ResponseYou've already chosen the best response.0\[2\cos (x)=\sqrt{3}\cot (x)\]

Best ResponseYou've already chosen the best response.0can you right cot (x) in terms of sin and cos

Best ResponseYou've already chosen the best response.0I wrote cot(x)=cos(x)/sin(x)

Best ResponseYou've already chosen the best response.0And then i cancelled the cos(x)

Best ResponseYou've already chosen the best response.0And i was left with sin(x) = sqrt(3)/2

Best ResponseYou've already chosen the best response.0now can you write what answer you got

Best ResponseYou've already chosen the best response.0I then thought i can get infinite answers....

Best ResponseYou've already chosen the best response.0So i wrote pi/3 and 2pi/3

Best ResponseYou've already chosen the best response.0I think there are more solutions but i dont know how to writee them

Rosh007

Best ResponseYou've already chosen the best response.0..... ok can you tell me what is th sin invers of \[\sin^{1}( \frac{ \sqrt{3} }{ 2 })\]

baddinlol

Best ResponseYou've already chosen the best response.0It is pi/3 and 2pi/3 between 0 and 2pi

Best ResponseYou've already chosen the best response.0I did pi  pi/3 because sin is also positive in that quadrant

Rosh007

Best ResponseYou've already chosen the best response.0yes exactly.. so when we find inverse if get more values we take the lesser value usually.. for example 7pi/3 is also giving same answer but by using the concept above answer will b what?

baddinlol

Best ResponseYou've already chosen the best response.0But i need to state all the values for it

baddinlol

Best ResponseYou've already chosen the best response.0so i need to write, pi/3, 2pi/3, 7pi/3, 8pi/3, 13pi/3, 14pi/3 .......

Best ResponseYou've already chosen the best response.0How can i write this as a general solution

Rosh007
 3 years ago
Best ResponseYou've already chosen the best response.0ok.. first take a look at pi/3 and 7pi/3 what can you find

Rosh007

Best ResponseYou've already chosen the best response.0any similarity?.. or relation... (clue can you relate with multiple of 2pi

baddinlol

Best ResponseYou've already chosen the best response.0Oo i think i found it

Rosh007

Best ResponseYou've already chosen the best response.0exactly.. ther you go... what is k...( no need to tll if you ar pretty sure)

Best ResponseYou've already chosen the best response.0Will i also need to evaluate cos(x)=0?

Rosh007

Best ResponseYou've already chosen the best response.0??? not clear... cab you make it more clear?is it another question?

Rosh007

Best ResponseYou've already chosen the best response.0if it is another qustion your answer is (2k+1)pi/2

baddinlol

Best ResponseYou've already chosen the best response.0wouldn't 2cos(x) = sqrt(3)cot(x) if cos(x) = 0 also

Rosh007
 3 years ago
Best ResponseYou've already chosen the best response.0ok...... asuming a fuction itself is zero may not lad you to corrct ansewr... also... here the cos (x) cancels each other (ofcourse before assuming it zero) hence assuming cos (x) = 0 is wrong..
