Question

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

Answer 1

Answer: yes

Step-by-step explanation:

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,

in this method we can find sin 25
