What is Theta when sin theta is 2?

Originally Answered: 2 sin theta =2-cos theta. What is the value of sin theta? Here, the amplitude (0 to 1 on top, 0 to -1 on bottom) remains unchanged, but the period changes (it is divided by 2). So a complete wave will have a period of 180 degrees/pi radians instead of 360/2 pi.

What value of sin equals 2?

0.0349
FAQs on Sin 2 Degrees Sin 2 degrees is the value of sine trigonometric function for an angle equal to 2 degrees. The value of sin 2° is 0.0349 (approx).

What is the value of theta for sin 2 theta is equal to 1?

15 degrees
The value of theta for which sin 2 theta equal to 1 is 15 degrees.

What is 2 sin theta cos theta?

The double angles sin(2theta) and cos(2theta) can be rewritten as sin(theta+theta) and cos(theta+theta). Applying the cosine and sine addition formulas, we find that sin(2theta)=2sin(theta)cos(theta). Sine of 2 theta equals 2 sine theta cosine theta.

What is sin 2 theta cos 2 theta?

Explanation: The answer is 1 , because sin2(−θ)=sin2θ and sin2θ+cos2θ=1 . Hopefully this helps!

How do you get the cos 2 theta?

The cosine double angle formula is cos(2theta)=cos2(theta) – sin2(theta). Combining this formula with the Pythagorean Identity, cos2(theta) + sin2(theta)=1, two other forms appear: cos(2theta)=2cos2(theta)-1 and cos(2theta)=1-2sin2(theta).

What is the formula of sin 2 theta in terms of tan theta?

Sin2x Formula in Terms of Tan We can write the formula of sin2x in terms of tan or tangent function only. For this, let us start with the sin2x formula. Therefore, the sin2x formula in terms of tan is sin2x = (2tan x)​/(1 + tan2x).

What is the maximum value of sin Theta?

The value of sin theta has a maximum value of 1 and a minimum value of -1. In this case, the domain of validity of the trigonometric identity csc theta which is the inverse of sin theta hence is ranging from negative infinity to positive infinity.

What is the sine of Theta?

When broken down, this represents that Sine (S) is equal to the length of the side opposite angle theta (O) divided by the length of the hypotenuse (H) so that Sin(X) = Opp/Hyp. Similarly, Cosine (C) is equal to the length of the adjacent side (A) divided by the hypotenuse.

What is the exact value of Cos 165?

For the answer to the question above asking to find the exact value of cos 165 degrees. The answer to this question is. cos 165 = cos (120+45) = cos120 cos 45 – sin 120 sin 45.

What is the sine of a 30 degree angle?

What is sin 30°. In a triangle which has one angle of 90 degrees, the sine of the angle of 30° is the ratio of the length of the opposite side o to the length of the hypotenuse h: sin 30° = o/h.
