Question

if x is equal to Sin inverse sin 10 and Y is equal to Cos inverse cos 10th then find the value of Y minus x

Answer 1

Answer

x = sin`1sin10 =10

y= 10

x-y=10

Step-by-step explanation:

Answer 2

HELLO DEAR,



as we know, sin-¹(sinx) = x [if , -90 < x < 90]
and cos-¹ (cosx) = x [if 0 < x < 180]

now,
given, x = sin-¹{sin(10)} & y = cos-¹{cos(10)}

so, x = 10 [if 0 < x < 90]

similarly,

y = cos-¹ (cos10) = 10 [if 0 < x < 180]

therefore, y - x = 10 - 10 = 0



I HOPE IT'S HELP YOU DEAR,
THANKS
