How do you find the value of tan 3 4?
The value of expression given is 36.86 degree.
What is the relation between tan theta and sin theta?
The relation between these trigonometric identities with the sides of the triangles can be given as follows: Sine (theta) = Opposite/Hypotenuse. Cos (theta) = Adjacent/Hypotenuse. Tan (theta) = Opposite/Adjacent.
What inverse tan 3?

| 0 | 0° | 0 |
| √33 | 30° | π6 |
| 1 | 45° | π4 |
What is sin Cos tan Theta?
Sin Cos Tan Formula Sine θ = Opposite side/Hypotenuse = BC/AC. Cos θ = Adjacent side/Hypotenuse = AB/AC. Tan θ = Opposite side/Adjacent side = BC/AB.
Is tangent Sin Cos?
The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
What is inverse sine?
The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.
How do you find inverse sine?
Inverse Sine Function
- Start with:sin a° = opposite/hypotenuse.
- sin a° = 18.88/30.
- Calculate 18.88/30:sin a° = 0.6293…
- Inverse Sine:a° = sin−1(0.6293…)
- Use a calculator to find sin−1(0.6293… ):a° = 39.0° (to 1 decimal place)
What quadrant is cos(theta) 3 in?
Since tan (theta)=3/4>0 and sin (theta)<0, theta is in quadrant 3 (since tan (theta)>0 iff theta is in quadrant 1 or 3 and sin (theta)<0 iff theta is in quadrant 3 or 4). cos (theta) must then be negative.

How to find the tangent of an equation with two solutions?
Take the inverse tangent of both sides of the equation to extract θ θ from inside the tangent. Evaluate arctan(− 3 4) arctan ( – 3 4). The tangent function is negative in the second and fourth quadrants. To find the second solution, subtract the reference angle from π π to find the solution in the third quadrant.
