Question

Guys, can we find the value of
Sin 25° like sin 30° is 1/2
If yes , then find it anyway
$.....$
​

Answer 1

Answer: yes

Step-by-step explanation:

we know that cos(2x)=2cos^2(x)-1

 x=15 degrees,  cos (15)  =SIN [75]

WKT sin(3x)=3sin(x)-4sin^3(x)

x=25, solve for the cubic equation in sin(x) using sin(75) value,

U get sin(25]
