Best ResponseYou've already chosen the best response.0Teacher:You cannot take terms across the = when doing a proof. You must show that the LHS=RHS. See if you can use cot^2(x)+1 = csc^2(x) to help you do this.??

Best ResponseYou've already chosen the best response.0looks like square not double angle that way the left hand side is correct

Best ResponseYou've already chosen the best response.2so the problem is: \[\cot^2(x)+\csc^2(x)=2\csc^2(x)1\]

Best ResponseYou've already chosen the best response.0this problem wants you to use the id 1+cot^2=csc^2

Best ResponseYou've already chosen the best response.2well let's play with this: \[\cot^2(x)+1=\csc^2(x)\] subtract 1 on both sides

Best ResponseYou've already chosen the best response.2this will isolate the cot^2(x) term

Best ResponseYou've already chosen the best response.2in then you will be able to write left hand side in terms of csc

Best ResponseYou've already chosen the best response.2do this one step: subtract 1 on both sides of cot^2(x)+1=csc^2(x)

Best ResponseYou've already chosen the best response.2if I asked you to subtract 1 on both sides of x+1=y what would you get after just doing that one step

Best ResponseYou've already chosen the best response.2i'm asking you to subtract one on both sides not one side remember whatever you do to one side of the equation you have to do to the other

Best ResponseYou've already chosen the best response.2x+1=y subtract 1 on both sides (x+1)1=y1 x+11=y1 x=y1

Best ResponseYou've already chosen the best response.2\[\cot^2(x)+1=\csc^2(x) \\ \text{ subtract 1 on both sides here }\]

Best ResponseYou've already chosen the best response.2right \[\cot^2(x)+\csc^2(x) \text{ was your left hand side } \\ \text{ replace} \cot^2(x) \text{ with } \csc^2(x)1\]

Best ResponseYou've already chosen the best response.2\[(\csc^2(x)1)+\csc^2(x) \\ \text{ you can drop ( ) } \\ \csc^2(x)1+\csc^2(x)\] do you think you can finish here:

Best ResponseYou've already chosen the best response.2you know how to combine like terms right?

Best ResponseYou've already chosen the best response.2examples of combining like terms: 5+5=2(5)=10 a+a=2a x^2+x^2=2x^2 log(x)+log(x)=2log(x) sin(x)+sin(x)=2sin(x) sin^2(x)+sin^2(x)=2sin^2(x) sin^2(x)+4sin^2(x)=5sin^2(x) can you find this: csc^2(x)+csc^2(x)=?

freckles

Best ResponseYou've already chosen the best response.2what happen to csc^2 's angle part?

freckles

Best ResponseYou've already chosen the best response.2csc^2 has no meaning csc^2(x) has meaning

freckles

Best ResponseYou've already chosen the best response.2something has to be plugged into the csc^2 function to actually have meaning csc^2 alone means nothing

freckles

Best ResponseYou've already chosen the best response.2so I think you meant to write 2csc^2(x) this does not mean csc^2 times x it means csc^2 of x like means x is being plugged into the csc^2( ) function

Best ResponseYou've already chosen the best response.2where does the extra x come from
