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.
Why can tangent values be greater than 1 but sine and cosine values cannot be greater than 1?
Sine and cosine cannot be greater than 1 because they are the Y and X values of a point on the unit circle. Tangent, on the other hand, is sine over cosine, so its domain is (-infinity,+infinity), with an asymptote occurring every odd pi/2.
How do you find amplitude in trigonometry?
The amplitude of a sine (or cosine) curve is the difference between the maximum and minimum values of the curve, measured over a whole cycle.
Tangentk equals 0.575 find angle k?
tan(k) = 0.575 so k = (0.5218 + k*pi) radians for all integer values of k.
Solve sin3x plus cos3x equals 6?
If you want sin(3x) + cos(3x) = 6, then this is impossible. Sine and cosine will only return values between -1 and 1, so the expression sin(3x) + cos(3x) could only take values from -2 to 2, although even this is to great as sine and cosine of the same number will never both be 1 or -1. Similarly, if you want a solution to sin3x + cos3x = 6, then this is also impossible, because any power of a number between -1 and 1 will itself be between -1 and 1.
What are the exact values of the sine and cosine functions of 2pi over 65537 in radians?
The answer will depend on whether the angles are measured in degrees or radians. That information is not provided and so the question cannot be answered.
What is cosine of 3?
Undefined!!!! Can't answer it! All sine and cosine values are between -1 and 1 !!!

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 does evaluate the expression in both radians and degrees mean?
Radians and degrees are two different systems for measuring the size of an angle. In radians, a full circle is 2pi radians. In degrees, a full circle is 360 degrees. If you want to evaluate an expression in both, then first simplify and evaluate the expression plugging in radian values into your trig functions. The second time, use degree values. On your calculator, you can switch modes between radians and degrees. It should give you the same answer unless you are supposed to leave it written as unevaluated trig functions or something like that. To convert from radians to degrees... radians=degrees * (pi/180)
How do you a graph trig functions?
The basic equation is of general form y = R(x) where (here) R is the Sine, Cosine or Tangent of x, and consequently the Sine and Cosine curves plot oppositely from +1 via 0 to -1 (minus 1) over 180º. The y-values of the Tangent curve goes cyclically from 0 to infinity as x goes from 0º to 90º: it looks odd at first, and you might even think you've gone wrong! Plot in the usual way: left-hand column or top row for suitable increments of x = [angle in degrees], neighbouring columns or rows below for the corresponding ratio values. To get the best out of it, plot 0º to 360º, to give a whole Sine Wave cycle - it and the Circle to which it can be related geometrically, being perhaps the 2 most important curves in Nature!
Sin and cosine values of 0?
sin 0 = 0 cos 0 = 1
When cosec is positive?
Between (2k)*pi radians and (1+2k)*pi radians where k is an integer. If you are still working with degrees, that is360*k degrees to (1+2k)*180 degrees, for integer values of k.NB: these are open intervals: that is, the end points are not included.Between (2k)*pi radians and (1+2k)*pi radians where k is an integer.

How do you make a cosine wave graph in Excel?
Enter the values you want to get a cos for in one column. In each cell in the next column, you will need a formula. Say your first value was in B2, then the formula would be:=COS(RADIANS(B2))Copy the formula so you have two sets of values. Select them all and start the chart wizard and use the XY Scatter graph, choosing the variation that links points with curved lines.
What are the important points you are to use in graphing the cosine function?
The basic cosine function is bounded by -1 and 1. It is a periodic function with a period of 2*pi radians (360 degrees). cos(0) = 1, cos(pi/2) = 0, cos(pi) = -1, cos(3pi/2) = 0, cos(pi) = 1. In between these values it forms a smooth curve. Also, it may help to understand that when the curve crosses the x-axis, its slope is 1 or -1.
