To find the value of sin^2(225°), you first convert 225° to radians because trigonometric functions typically work with radians. Since 1 full rotation in degrees equals 2π radians, you can convert 225° to radians by multiplying by (π/180):
225° * (π/180) = (5π/4) radians
Now, sin^2(225°) is equivalent to sin^2((5π/4)). Using the identity sin^2(x) = (sin(x))^2, you simply need to square the sine of (5π/4):
sin(5π/4) = -√2/2
Now, square this value:
(sin(5π/4))^2 = (-√2/2)^2 = 2/4 = 1/2
So, the value of sin^2(225°) is 1/2.
