Do y -y1 = m(x-x1) to find the general equation of a tangent using x =2t y =1/t
Find the x and y intercepts by subbing in 0 for x and y
Then the Area = 1/2 x OQ X OR = 8 which is independent of t
Okay lol I did all that but thought I was completely wrong. I guessed that t = 1 and didn't say that the area was independent of t so will I lose a mark for not explaining
[QUOTE="Man;66069181" Mr="Mr" Moon="Moon"]P=2 Q=-2[/QUOTE Fgs ended up with 4 and -4, must have lost a half somewhere! Reckon I'll get any marks for setting up the equations and follow through for validity?
-Root10cos(theta+1.249) -Invalid because4/root10 is bigger than 1 -P=2,Q=-2 -Theta=90,26...? -volume=16Pie/3 Area was 8 -Q(12/5,8/5,2) not sure about y here Ratio 3:2? Last q was show thats and k=0.811?

Was it not 8pi/3 as it was only rotated through 180 degrees
