Sin2x=2sinxcosx
sin2x/5=2sinx/5cosx/5
hence the nuber 2 multiply by cosx/5sinx/5 can be divided on the other side
hence its true
You need to shift the decimal 3 spaces to the left, which would get you 0.0034.
Using the formula for the nth term of an arithmetic progression.
an = a + (n - 1)d
a(4) = a + 3d = 55
a(9) = a + 8d = 90
a(9) - a(4) => 5d = 35
d = 35/5 = 7.
From a(4): a = 55 - 3d = 55 - 3(7) = 55 - 21 = 34
a(2) = a + d = 34 + 7 = 41.
