I will note x instead of theta
tan(x) = sin(x) / cos(x) = 1/4
sin(x) = cos(x)/4 = ±sqrt(1-sin2x)/4 as cos2x + sin2 x = 1
4 sin(x) = ±sqrt(1-sin2x)
16 sin2x = 1-sin2x
17 sin2x = 1
sin2x = 1/17
sin(x) = ±1/sqrt(17)
2 sin^2 theta = 1/4 sin^2 theta = 1/8 sin theta = sqrt(1/8) theta = arcsin(sqrt(1/8))
One-fourth of an hour is 15 minutes, since an hour consists of 60 minutes. To find one-fourth, you divide 60 by 4, which equals 15.
No. one fourth equals 0.25.
A half/one half.
To find one fourth of a number, you divide the number by 4. This is equivalent to multiplying the number by 1/4. For example, to find one fourth of 20, you would divide 20 by 4, which equals 5. So, one fourth of 20 is 5.
One fourth of 40,000 is 10,000. To find one fourth of a number, you divide the number by 4. In this case, 40,000 divided by 4 equals 10,000. Therefore, one fourth of 40,000 is 10,000.

9 inches equals one fourth yard.
Um... Three one eighth teaspoons do not equal a three fourth teaspoon. Think about it. Three one eighth teaspoons equal three-eighths and three-eighths are not equivalent to a three fourth teaspoon.
One fourth of 5000 is calculated by dividing 5000 by 4, which equals 1250. To find one fourth of a number, you divide that number by 4, as the fraction 1/4 represents dividing something into four equal parts. Therefore, one fourth of 5000 is 1250.
No, it equals one eighth.
