2sin(y) = 2x/sqrt(1+x^2)
tan(b) = x/sqrt(y^2-x^2)
it equals 4
x = 45 degrees sin(x) = cos(x) = 1/2 sqrt(2)
Theta equals 0 or pi.
sin45=1/root 21/root 2 = x/ycos45= 1/root 2x/y= 1/root 2x=y/root 2
22.20366435 sin^-1(0.3779)
The value of sine and cosine varies between -1 and 1, it never can be 12. If you mean .12, then we have: sin x = .12 x = sin-1 .12 x = 6.89 degrees So that, cos x = cos 6.89 = .99
The expression (\sin(3\alpha)) can be expanded using the triple angle formula for sine, which is (\sin(3\alpha) = 3\sin(\alpha) - 4\sin^3(\alpha)). This formula allows you to express (\sin(3\alpha)) in terms of (\sin(\alpha)).
It is zero.

Assuming sin equals 0.3237, the angle is in quadrant I.
y = sin(-x)Amplitude = 1Period = 2 pi
