## Is tan theta 0 possible?

Prove that the general solution of tan θ = 0 is θ = nπ, n ∈ Z. Solution: According to the figure, by definition, we have, Tangent function is defined as the ratio of the side perpendicular divided by the adjacent.

### What does tan theta equal 0?

Trigonometry Ratio Table of Different Angles

What does sin θ 0 mean?

The sin of an angle is based on a right triangle in standard position and is defined as the side opposite the angle divided by the hypotenuse. If sin(θ)=0 then the side opposite the angle θ must have a length of 0.

In which quadrant does θ lie if the following statements are true tan theta 0 \text and sin theta 0?

Accordingly, both tanθandsinθ are < 0 in the fourth quadrant Q4.

## Where is tan theta 0 on the unit circle?

For an angle in the first quadrant the point P has positive x and y coordinates. Therefore: In Quadrant I, cos(θ) > 0, sin(θ) > 0 and tan(θ) > 0 (All positive).

### Where is tan theta equal to?

In right triangle trigonometry (for acute angles only), the tangent is defined as the ratio of the opposite side to the adjacent side. The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta).

Why is sin 2pi 0?

We also know that 0° corresponds to the point (1, 0) on the unit circle (as it is a point on the unit circle present on the x-axis). Thus, sin 2π = sin 0° = y-coordinate of (1, 0) = 0. Hence, sin 2π = 0.

Is tan positive or negative?

Quadrants and the “cast” Rule In the first quadrant, the values for sin, cos and tan are positive. In the second quadrant, the values for sin are positive only. In the third quadrant, the values for tan are positive only.

## Which quadrant does θ lie in?

In general, if θ lies in the third quadrant, then the acute angle θ−180∘ is called the related angle for θ. Use the method illustrated above to find the trigonometric ratios of 330∘.

### What is tan θ equal to?

or, tan theta = sin theta/cos theta (here, theta is an angle) The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side, while the cosine of an angle is the ratio of the adjacent side to the hypotenuse side. Hence, sin x = Opposite Side/Hypotenuse Side.

At what angle is tan theta 0?

θ sin θ tan θ
0 0
90° 1 undefined
180° 0 0
270° −1 undefined

How do you solve sin Theta?

To solve, isolate the sine of the unknown angle by multiplying both sides of the equation by the length of angle theta’s opposite side. For example: sin A/a = sin B/b becomes (b * sin A)/a = sin B. In a calculator, given side a = 5, side b = 7, and angle A = 45 degrees, this is seen as SIN^-1((7*SIN(45))/5).

## What are the six trigonometric identities?

The six trigonometric functions are called sine, cosine, tangent, cosecant, secant, and cotangent. Their domain consists of real numbers, but they only have practical purposes when these real numbers are angle measures. Consider an angle θ in standard position. Take a point P anywhere on the terminal side of the angle.

### What is SEC theta equal to?

So, as an answer to your question, sec theta is equal to 5/4.

What is cos theta equal to?

Theta, cosine of theta is equal to negative one when we’re at this point on the unit circle. So that happens when we get to pi radians, and then it won’t happen again until we get to two pi, three pi radians, three pi radians.
