(a) find the unit vectors that are parallel to the tangent line to the curve y = 2 sin(x) at the point (π/6, 1). (enter your answer as a comma-separated list of vectors.) (b) find the unit vectors that are perpendicular to the tangent line. (c) sketch the curve y = 2 sin(x) and the vectors in parts (a) and (b), all starting at (π/6, 1)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
