Questions by Lawson from Markham, VA
Find two unique functions that satisfy the conditions P(-4) = P(-3/4) = P(1/2) = 0 and p(-2) = 60 Family of polynomials
sec^2 x - tan ^4 x = 3 Solve for x
How can you do this without plugging it into a graphing caculator?
cosx = (1- tan^2 x/2) / 1 + tan^2 x/2) Completely stuck.
Explain how you could determine the exact value of (sec 7pi/6) if you know the value of (sin 11pi/6). Prove with diagrams. I've no idea how to do this question that's worth 10 marks...
Prove 1 - sin2x / cosx = sin2x / 2sinx I tried do both LHS and RHS. Got stuck after a step or two.
Prove sec2x = 1 + tan2x I did R.H.S = 1 + sin2x / cos2x = 1 + (1 - cos2x) / (1 - sin2x) = 1 + cot2x = ??? I think I'm doing it right,...
