No. Sin of any angle is always less than or equal to 1.
2 sin2(x) + sin(x) - 1 = 0(2 sin + 1) (sin - 1) = 0Either 2 sin(x) + 1 = 02sin(x) = -1sin(x) = -0.5x = 210°, 330°or sin(x) - 1 = 0sin(x) = 1x = 90°
sin2 + cos2 = 1 So, (1 - 2*cos2)/(sin*cos) = (sin2 + cos2 - 2*cos2)/(sin*cos) = (sin2 - cos2)/(sin*cos) = sin2/(sin*cos) - cos2/(sin*cos) = sin/cos - cos-sin = tan - cot
You can look up "trigonometric identities" in Wikipedia.Cos(2x), among other things, is equal to (cos x)^2 - (sin x)^2 If you meant cos squared x, or (cos x)^2, that is equal to (1 + cos(2x))/2
sin(pi/2)=1
sin2csc2-sin2 (using the fact that the sin is the reciprocal of csc) = 1-sin2
sin-30 = (-1) x 1/(square root of 2) -sin30 = -(1/square root of 2) They are equal
1/2 of sin(2x)
because sin(2x) = 2sin(x)cos(x)
It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!
Sin(x) cos(x) = 1/2 of sin(2x)
sin 480° is equal to sin 60°, which is sqrt(3)/2 or approximately 0.866.
sin(pi/4) and cos(pi/4) are both the same. They both equal (√2)/2≈0.7071■
Cos(2x) = cos^2(x) - sin^2(x) = 2 cos^2(x) - 1 = 1 - 2 sin^2(x).Source: ChaCha.com
Cos^2 x = 1 - sin^2 x
yeah. a sin is still a sin.
Sin squared is equal to 1 - cos squared.
