First of all, I can't tell what angle you're talking about, because you failed
to mention the unit of your angle.
-- Cosine of 16 degrees is roughly 0.9613 ... a positive number.
-- Cosine of 16 radians is roughly -0.9577 ... a negative number.
-- Cosine of 16 grads is roughly 0.9686 ... a positive number.
Over any reasonably large range of angles, half of them have positive cosines,
and the other half of them have negative cosines.
What else can I help you with?
Why do cosine to the negative 1th power and cosine cancel out each other?
Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
What are the Differentiate the sine wave and cosine wave?
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
What is the answer to cosine x equal to negative one?
cosine(x) = -1x = (270 + 360N) degreesorx = (1.5 + 2N) pi radiansN is any integer, positive or negative.
Which quadrant is sine positive and cosine negative?
Sine is positive and cosine is negative in the second quadrant of the Cartesian coordinate system. In this quadrant, the angle is between 90 and 180 degrees, where the y-coordinate (sine) is positive and the x-coordinate (cosine) is negative. Thus, for any angle in the second quadrant, sine values are above the x-axis, while cosine values are below it.
What is the derivative of negative cosine?
The derivative of negative cosine is positive sine.
Why do cosine to the negative 1th power and cosine cancel out each other?
Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.
Why are cosines positive and negative?
Because the cosine of some angles is positive and the cosine of some other angles is negative.
Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
What are the Differentiate the sine wave and cosine wave?
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
What is cosine to the negative first power?
[ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ)
What is the difference between negative sine and cosine graphs and positive sine and cosine graphs?
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
In what quadrant is cosine negative and cotangent negative?
The second quadrant (top left).
What is the anti derivative of negative sine?
The anti derivative of negative sine is cosine.
What is the answer to cosine x equal to negative one?
cosine(x) = -1x = (270 + 360N) degreesorx = (1.5 + 2N) pi radiansN is any integer, positive or negative.
Which quadrant is sine positive and cosine negative?
Sine is positive and cosine is negative in the second quadrant of the Cartesian coordinate system. In this quadrant, the angle is between 90 and 180 degrees, where the y-coordinate (sine) is positive and the x-coordinate (cosine) is negative. Thus, for any angle in the second quadrant, sine values are above the x-axis, while cosine values are below it.
What is the value of the angle in which the sine and cosine are equal and both negative?
225 degrees
