how do you start this equation i've been tryng it for 20min. sec^6x(secxtanx)-sec^4x(secxtanx)=sec^5xtan^3x ec^6x(secxtanx)-sec^4x(secxtanx)=sec^5xtan^3x Factor out a sec^5 tan and divide thru. Left is sec^2 x = Tan^2 x Then this should reduce to sin^2 x = cos^4 x take the ...

This deals with quadratic functions-If I have a graph with he = (-5)and k =3 and they ask for the translation, would it be {5,3} or would the translation just be {-5,3} Do you take the opposite of the number when it is transalated from the graph or do you only take the ...
