Best ResponseYou've already chosen the best response.2so its \(\huge \dfrac{1}{\cot^2 \theta + \sec \theta \cos \theta} \)

Best ResponseYou've already chosen the best response.2firstly, use the identity that sec theta = 1/cos theta so, sec theta cos theta = 1 and do you know what is \(\large 1+\cot^2 \theta = ... ?\)

Best ResponseYou've already chosen the best response.0only the cot^2theta is the denominator

Best ResponseYou've already chosen the best response.0no I don't know, I am COMPLETELY lost in this subject

Best ResponseYou've already chosen the best response.2okk., so anyways you can use sec theta cos theta = 1 \(\large \dfrac{1}{\cot^2 \theta }+1 \)

Best ResponseYou've already chosen the best response.2now 1/ cot theta = tan theta so, \(\large \tan^2 \theta+1 \)

Best ResponseYou've already chosen the best response.2and ther's a standard pythagorean identity that \(\large 1+\tan^2 \theta = \sec^2 \theta \) thats it! :)

Best ResponseYou've already chosen the best response.0Simplify the expression. quantity cosecant of x to the power of two times secant of x to the power of two divided by quantity secant of x to the power of two plus cosecant of x to the power of two.

Best ResponseYou've already chosen the best response.2ok, we use the identity that csc x = 1/ sin x sec x = 1/cos x

Best ResponseYou've already chosen the best response.2\(\large \dfrac{\csc^2 x \sec^2 x }{\sec^2 x + \csc^2 x } = \large \dfrac{\sin^2 x \cos^2 x }{\sin^2 x + \cos^2 x }\)

Best ResponseYou've already chosen the best response.2now we can use the famous pythagorean identity \(\Large \color{red}{\sin^2x + \cos^2 x =1 }\)

Best ResponseYou've already chosen the best response.2what remains is your answer! :)

Best ResponseYou've already chosen the best response.0so the answer is just 1? or am I wrong?

hartnn

Best ResponseYou've already chosen the best response.2denominator = 1 yes what remains is numerator sin^2 x cos^2 x

Best ResponseYou've already chosen the best response.2you have choices for this too ?

anonymous

Best ResponseYou've already chosen the best response.0yes I do the choices are: sin^2x cos^2x 1 1

Best ResponseYou've already chosen the best response.0im sorry im so stupid. im usually really good at math but precalc just makes no sense to me

hartnn

Best ResponseYou've already chosen the best response.2oops, i did a simplification error \(\large \dfrac{\csc^2 x \sec^2 x }{\sec^2 x + \csc^2 x } = \large \dfrac{1 }{\sin^2 x + \cos^2 x } = 1\)

Best ResponseYou've already chosen the best response.0okay and i have a question. next year I planned on taking ap stat. is that anything like precalc because i hope not. is it easier or harder?

hartnn

Best ResponseYou've already chosen the best response.2if you practice less, math is hard. if you practice more, math is easy. irrespective of any topic/subject

Best ResponseYou've already chosen the best response.0well are the concepts of ap stat very similar to or very different to those of precalculus?

hartnn

Best ResponseYou've already chosen the best response.2statistics is a different branch of math altogether, so very different.

Best ResponseYou've already chosen the best response.0i just think I'm not good at online class taking because I learn better from an actual person rather than a computer screen. I need the physical classroom environment and a teacher to give me instruction.

Best ResponseYou've already chosen the best response.0what kind of problems does ap stat entail? word problems? graphs?

anonymous

Best ResponseYou've already chosen the best response.0oh okay thank you soooooo much! is there anything else that i should know?
