Question

If x and y are the angles lying in the second quadrant and x<y, then which one of the following is true?
(a) sinx=siny (b) sinx<siny
(c) sinx>siny (d) None of these,
Please provide detailed solution​

Answer 1

Answer:

only option c is correct.

because in second quadrant the graph of sinx is decreasing.

therefore according to definition of decreasing function, if x < y then sinx > siny
