Not sure that your answer method to Q2a is on the curriculum, diff of sinx (?) Alternate is to see the period of this sine function is 4 pi (from 2pi divided by 1/2). So visually, x coordinate of A is therefore going to be 3 pi as midway between (2 pi, 0) and (4 pi, 0) through symmetry.
for question number 2b, after transformation to get min y=2-k shouldnt it happen when x=pi, as it has to be -k for the sin function. As if you take x=3pi, then sin function becomes negative and results in y to be 2+k, *NOT 2-k *
@taskeendaiyan1522 the two transformations- verical translation and reflection do not change x coordinate. Remember, the function is not same as original now.
@@mathunitedofficial but they do change the shape, so minimum turning point becomes the maximum point and the same vice versa, so the x coordinates for the maximum point would definitely change. As A is defined as the minimum turning point.

You are right. Just 2 marks could be earned directly.
Question 2a - Differentiation of sin (x) is not in the AS Syllabus
its in the List MF19 page 3 go check it out

I got 2+k only.
@@mathunitedofficial yes but the x coordinates must change, for to get the y coordinates 2+k. So x must be pi to get that

@taskeendaiyan1522 Thats true. However, they saskrd ' the point corresponding to A'.
COULD YOU ALSO POST FOR PHYSICS PAPER 42 FEB MARCH
how is sin 3pi/2 = 1?
im lost there too😅😅
@@KaamaelKumar 😭😭right
Use the radians function on your calculator, so in rad, 3π/2 = -1
can I get the Stat 2 paper(P6) Please
