What is the exact value of sin 3 pi?
What is the exact value of sin 3 pi?
The exact value of sin(π3) sin ( π 3 ) is √32 .
What is the exact value of sin 3 pi by 2?
The exact value of sin(π2) sin ( π 2 ) is 1 .
Why is sin 3pi 2?
Explanation: In standard position, an angle of 3π2 has a hypotenuse which falls along the negative Y-axis. If a hypotenuse of unit length is swung towards the negative Y-axis, the side opposite the origin approaches -1.
What is sin 0 on the unit circle?
Sin 0 signifies that the value of x coordinate is 1 and the value of y coordinate is 0,i.e. (x,y) is (1,0). That means the value of the opposite side or perpendicular is zero and the value of hypotenuse is 1.
Which of the following is value of sin 90?
The correct alternative answer for the multiple-choice question will be 1. We have to find the value of Sin90° and there are four options given for that. As we know value of Sin90° = 1. So, the correct answer will be option D.
Why is sin 90 a cosa?
All triangles have 3 angles that add to 180 degrees. Therefore, if one angle is 90 degrees we can figure out Sin Theta = Cos (90 – Theta) and Cos Theta = Sin (90 – Theta).
Why is TAN 90 and TAN 270 undefined?
At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. At 270 degrees we again have an undefined (und) result because we cannot divide by zero..
What is the value of sin 7pi 4?
The exact value of sin(π4) sin ( π 4 ) is √22 .
What is one angle where Tanθ is undefined?
| θ | sin θ | tan θ |
|---|---|---|
| 90° | 1 | undefined |
| 180° | 0 | 0 |
| 270° | −1 | undefined |
| 360° | 0 | 0 |
How do you solve COS 180 degrees?
The value of sin 90 degree is 1. Therefore, the value of cos 180° is -1. The value of trigonometric ratios for different angles are given for the reference….
