If sin θ = tan θ, that means cos θ is 1 (since tan θ = (sin θ)/(cos θ))
(Usually in and equation a/b=a, b doesn't have to be 1 when a is 0, but cos θ = 1 if and only if sin θ = 0)
The angles that satisfy cos θ = 1 is 2n(pi) (or 360n in degrees)
When n is an integer.
But if sin θ = tan θ = θ, the only answer is θ = 0.
Because sin 0 is 0 and cos 0 is 1 and tan 0 is 0
The only answer would be when θ = 0.

What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
What is the arc sine of 1.5 degrees?
if x if ArcSine 1.5 degrees means the sin(x)=1.5 but the range of the sin(theta) for all angles theta is between o and 1 inclusive. So there is no real answer.
What is the value of theta when sine of theta is 0.91?
sin-1 (0.91) = about 1.14328 radians.
How is tangent defined?
The tangent of an angle theta is defined as sine(theta) divided by cosine(theta). Since the sine and cosine are Y and X on the unit circle, then tangent(theta) is Y divided by X. The tangent of a function at a point is the line going through that point which has slope equal to the first deriviative of the function at that point.
What is sine in math?
Sine is a law in math that helps you find the length or angles in a triangle.Sin Equals:1/YLaw of Sines:Sin A/a = SinB/b = SinC/cCosine, tangent, cotangent, secant and cosecant are also used to find sides and angles of a triangle.
Can sine theta equals tan theta equals theta be equal for small angels?
Yes. (Theta in radians, and then approximately, not exactly.)
What is cosine 2 theta when sine theta equals .28?
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
What is the value of sine theta when theta is equal to 0.4384?
We'll answer your question as asked. What was asked was, "What is the sine of the angle (the angle theta) if the angle measures 0.4384?" That's the way the question reads. That's a pretty small angle. Less than one degree. That angle has about 0.00765 as the sine. Perhaps the question was "What is the angle of theta if its sine is 0.4384?" In the event that this was really your question, if sine theta equals 0.4384, arcsine theta is about 23.00 degrees. Here we use the term arcsine. If we see "arcsine 0.4384" in a text, what it means is "the angle whose sine is 0.4384" in math speak.
What is angle Theta if sine theta 0.03125?
-1 < sine(theta) < 1 so sine(theta) cannot be 3125
Can sine theta equals to theta?
Yes, it can. If you plot theta and sin(theta) on the same graph, you will see where they intersect. I do not know of an analytical expression for this point; I think only numerical results are possible.
What is the equivalent of sine theta over secant theta?
For such simplifications, it is usually convenient to convert any trigonometric function that is not sine or cosine, into sine or cosine. In this case, you have: sin theta / sec theta = sin theta / (1/cos theta) = sin theta cos theta.
Is sin squared theta and sin theta squared the same?
Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.
What does sine theta mean?
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
What is sine theta?
The sine theta of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
What is cos 90 minus theta?
cosine (90- theta) = sine (theta)
Sine 2 theta sine4 theta 0?
That is not a question.
