Is tangent sine divided by cosine?
Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.
What are the values of theta of which secant theta is undefined?
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.
What is cosine 0?
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
What is the domain of the cosine function?
-1<cosine<1
What is the formula for the y-intercept of a cosine function?
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
What is the cosine of 90 degrees?
The cosine of 90 degrees is zero.
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
What is the value cosine 90?
Zero
What is cos 90?
Cosine of 90 degrees is zero.
Is tangent sine divided by cosine?
Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.
When is secant not defined?
The secant of an angle is the reciprocal of the cosine of the angle. So the secant is not defined whenever the cosine is zero That is, whenever the angle is a multiple of 180 degrees (or pi radians).
What are the values of theta of which secant theta is undefined?
Since secant theta is the same as 1 / cosine theta, the answer is any values for which cosine theta is zero, for example, pi/2.
What is cosine cubed?
It is cosine*cosine*cosine.
What are the keypoints for the graph of cosine?
For a general cosine graph, they would be the maximum and minimum values, and the values of the independent variable at which these are attained.Note that the graph of y = cos(x)+2 is never equal to zero, so there may not be any roots.
What is tangent of 0?
Zero. Tangent = sine/cosine. sin(0) = 0 and cos(0) = 1, so 0/1 = 0.
Which case cosine function becomes zero?
For an angle of 90 or 270 degrees. In radians, pi / 2 and 3 x pi / 2.
Why is it true that the cosine of 0 equals 1?
A cosine of a triangle is the length of the leg adjacent to a specific angle divided by the hypotenuse. Another way of putting it is that a cosine of an angle is x/r, or the x-coordinate of the endpoint divided by the distance of the endpoint from the origin. In trigonometry, if this angle were to be zero radians or zero degrees, the triangle would become a short, flat line pointing directly to the right. In that case, the distance of the endpoint from the origin and the x-value of this point are one and the same. Thus, the ratio between them is 1, and the cosine of zero is 1. Also, the power series for cosine is as follows (where the angle is in radians): cos(x) = 1 - x^2/2 + x^4/24 - x^6/720 - x^8/40320 + ... (The denominators are the factorials of even numbers.) If you put x=0, you get cos(0)=1.
