Answer:

Step-by-step explanation:

Given

a sinxcosx

b

\frac{1}{2} sin2x = \frac{1}{2} × 2sinxcosx = sinxcosx

c

sin²x × \frac{cos^2x}{sin^2x} = cos²x

d

\frac{sinx}{cosx} × cos²x = sinxcosx

Hence c is the expression not equal to the others

1. A square ABCD has the vertices A(n, n), B(n, -n), C(-n, -n), and D(-n, n). Which vertex is in Quadrant III?
andrew-mc [135]

The four quadrants and the sign of coordinates is given as follows:

Quadrant I : (n, n ) both x and y positive.

Quadrant II : ( -n,n) = x negative and y positive.

Quadrant III : ( -n,-n) = both x and y negative.

Quadrant IV: (n, -n) = x positive and y negative.

So Based on the above concept , we can say that vertex C (-n,-n) has both x and y negative and so it lies in quadrant III.

Answer is Vertex C (-n,-n)
