will it work ?
2020-04-01 16:23
sometimes it work sometimes it doesnt but if it does it shows you the answer and the steps on how to do it
2020-04-01 16:24
use subsituition on cos2x for example cos t and then calculate what T is 1-cos(t) cos^-1(1) = t

This is too unclear for me
2020-04-01 16:31
c)2cos(2x) -1 = cos4x (formula, btw) d) 1 - cos2x = 2sin^2(x) e)sqrt(2)- 2cos(x)= 2(sqrt(2)/2 - cos(x)) = 2(cos(pi/4) - cos(x)) = -4sin((x+pi/4)/2)*sin(x-pi/4)/2)

a)sin86+cos84= E=mc2 b)cos 75+sin75= Sincos 150 c)2 cos2x – 1 = 69 d) 1 – cos2x = 420 e)V2-2 cosx = 12

C) 2cos(2x)-1=0 2cos2x =1 2x = arccos 1/2 X=pi/6, oh wrong, it's not equal to 0. #15 did it.

I was one of the best at this in my highschool and I have no idea anymore, havent really used my brain for 2 years. I have a really good memory tho, If I start studing again I will remember it quickly.
