Question

Without actually drawing figures or looking up tables, can you arrange the numbers below in ascending order?
Sin 1°, cos 1°, sin2°, cos 2°

Answer 1

Step-by-step explanation:

Sine is an increasing function and cosine is a decreasing function.

correct order would be

cos1>cos2>sin2>sin1

Answer 2

Answer:

The required ascending order is given below.

sin (1°) < sin (2°) < cos (2°) < cos (1°)

i.e., 0.0174524 < 0.0348995 < 0.999391 < 0.999848
