A bag of salt was projected vertically upwards from a height of 1 and remains in the air for 6.1 s. (a) What speed was the bag thrown at, and (b) What was the distance the bag travelled before returning to the height of 1 m?

Thank you so much! @Herowise and also @Integrand. Just that for Q2, I think you swapped the pi/6 with pi/2. Otherwise all steps are clear! <3

Find the general solution for: Q1: sin x + cos x = 1 Q2: √3 cosx - sinx = 1 Thanks!

Thank you so much! That makes a lot of sense and was really easy to follow.

The equation x3-bx2+cx-d = 0, where d>0, has roots α, ß and αß. Show that (c+d)2 = (b+1)2d. New to forums and not sure if this is how things are done. Sorry in advance! And thanks!

Thanks this helps, (12 years later)!
