Question

How do you evaluate sin(45)cos(15)+cos(45)sin(15)?​

Answer 1

Step-by-step explanation:

IT'S A SIMPLE FORMULA BASED QUESTION..

if you are a 11th or 12th science student then you know this formula,

sin(a+b) = sin(a)cos(b) + cos(a)sin(b)

so use it here....

sin(45)cos(15) + cos(45)sin(15)

here a = 45 and b = 15

so,

sin(a+b) = sin (45 + 15)

-> sin(60)

->

$\frac{ \sqrt{3} }{2}$

HOPE IT HELPS..
