    actually i wrote the question wrong it's actually 3-2(cos(x^2))x - 3sinx =0 and i got it mixed up with 2sin(^2)x + cos x -2 = 0 mind doing both of them? both are between 0 and 360 degrees

    Answer: a) a=1, d=4 Sn = (n/2)[2a+(n-1)d] = (n/2) [2(1)+(n-1)4) = (n/2) [3+4n-4) = (n/2) [4n-1] = n[8n-2] = 8(n^2)-2n b) a=3, d=4 Sn = (n/2) [2(3)+(n-1)4] = (n/2) [6+4n-4] = (n/2) [4n+2] = n(8n+4) = 8(n^2)+4n i) a=-4, d=-8 Sn =...
