What is the unit of pi?
What is the unit of pi?
Pi has no measuring unit. Pi is the ratio between the circumference and the diameter of a circle, so that: C/D=π.
What is the value of minus sin pi by 2?
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because sine is negative in the fourth quadrant. The exact value of sin(π2) sin ( π 2 ) is 1 .
What is the value of sin PI by 12?
Check by calculator. Calculator –> sin(π12)=sin15∘=0.26 .
How do you find the value of sin PI 4?
The exact value of sin(π4) sin ( π 4 ) is √22 .
How do you find the value of sin pi?
What is the value of sin pi? In trigonometry, we use pi (π) for 180 degrees to represent the angle in radians. Hence, sin π is equal to sin 180 or sin π = 0.
What is the value of sin Pi Theta?
sin(π – θ) = +sinθ, cos(π – θ) = -cosθ, tan(π – θ) = -tanθ, cot(π – θ) = -cotθ.
What is cosine times pi?
The cosine of pi is equal to -1.
What is the value of sin 90 in fraction?
1/ 1
What is the sin of 60 in degrees?
From the above equations, we get sin 60 degrees exact value as √3/2. In the same way, we can find the values for cos and tan ratios.
What is the value of sin 30 degrees in fraction?
1/ 2
What is the value of sin 45 degrees in fraction?
Sin 45° = \sqrt{2/4} = 1/\sqrt{2}
| Sine 0° | 0 |
|---|---|
| Sine 30° or Sine π/6 | 1/2 |
| Sine 45° or Sine π/4 | 1/\sqrt{2} |
| Sine 60°or Sine π/3 | \sqrt{3}/2 |
| Sine 90° or Sine π/2 | 1 |
What is the value of Cosec 0 degree?
The value of cosec at 0° is the reciprocal of sin at 0°.
What is the value of TAN 60 in fraction?
30 Degrees
| Angle | Tan=Sin/Cos |
|---|---|
| 30° | 1 √3 = √3 3 |
| 45° | 1 |
| 60° | √3 |
Is tan 60 degrees greater or less than 1?
By inspection, tan 60 = y/x = 3 1/2 which is obviously more than 1. tan 30 = 1/2 divide by a number greater than 1, which obviously results in a number less than 1.
What is the value of Cosec 60?
The value of cosec 60 degrees or cosec pi/3 is 2/√3.
What is the formula of tan 60 degree?
Draw a perpendicular line AD from A to BC. In the same way, we can derive other values of tan degrees like 0°, 30°, 45°, 90°, 180°, 270° and 360°….Learn More:
