wow thanks a lot is this the standard method of doing it? so whenever we need to prove sth like, cos something + cos something = something We always equating the "z" on both side. cos something x cos something = something we always sub z = i to get the answer am i correct?

now we know: z^5 -1 / z-1 = (Z^2 - 2z cos 2pie/5 +1 ) (z^2 - 2zcos 4pie/5 +1) we need to show: cos2pie/5 + cos4pie/5 = - 1/2 AND cos2pie/5 x cos4pie/5 = -1/4 How to use the comparing coefficient method? and besides this method, any other ways to use? THANKSSSSSSSSSSS!!!!!!!!!!

Thanks guys~~~

1.) Write both Carterian equation and the parametric equation for the conic which has foci (-6, -2) and (4, -2), and an eccentricity of 5/4 ans: [(x+1)^2]/25 - [16(y+2)^2]/225 = 1 x = 5sec日-1 y=(15/4)tan日=2 2.) Find the equation of the normal to the ellipse x^2 /100 + y^2 /...

OH THANKS~!!! but the link is not working =(

1. Prove (x^4)/4 + (x^3)/3 + (x^2)/2 + x + C has no real zeros if C > 7/12 Teacher told us to find the min.tp, and show that the y value of the tp is < 0, then there will be no real zero. but how about max tp? if a say max tp with is < 0, is it also no real zeros? another question, if C <...

i asked my teacher and he said he doesnt have a CD =(

thankyou everyone :D:D:D
