I'm not whether this is the right place, but I saw geometry, n differentiation n thought, hmm, my question kinda involves both. If its in the wrong place, sorry... Anyways...Got this curve given as :biggrin: = theta for the sake of typing, hehe. x = a cos :biggrin: y = b sin...

Well, I'm a Brit so I'm not 2 sure about the exact work u'll be doing, but we're doing the same sort of topics in calc at the moment. We do modules of pure maths alongside others like statistics and decision. The topics look much harder than they are. I kno when I first started em, they LOOK...

Right, I'm gettin irritated by these :confused: , hehe, I need some expert quidance on how to do all kindsa questions with these, mainly the more complicated 1's where u can't just sub in values of x to get 0. Lotsa input will be appreciated :smile:

Hmm...k well...I tried usin ur advice n I got... dy/dx = (3x^2 - 3y^2) / (3y^2 + 6xy) for the whole thing...is that right? cos if so I'm not 2 sure bout how to find exact turning points, i kno it has to equal 0 but if u multiply through by the denominator, ur left with 0 = 3x^2 - 3y^2 ...so...

Thanx a lot! Think I got it sorted now then, I'm off 2 try it out

find the turning points on the curve with equation y^3 + 3xy^2 - x^3 = 3 I'm confused bout the 3xy^2 mostly, i kno that xy goes to (y+x dy/dx) but not sure what 2 do bout the power...
