How do I find the value of tan 225?

How do I find the value of tan 225?

The value of tan 225 degrees is 1. Tan 225 degrees in radians is written as tan (225° × π/180°), i.e., tan (5π/4) or tan (3.926990. . .)….We can use trigonometric identities to represent tan 225° as,

  1. cot(90° – 225°) = cot(-135°)
  2. -cot(90° + 225°) = -cot 315°
  3. -tan (180° – 225°) = -tan(-45°)

How do you find COS 225 without a calculator?

⇒ 225 degrees = 225° × (π/180°) rad = 5π/4 or 3.9269 . . . ∴ cos 225° = cos(3.9269) = -(1/√2) or -0.7071067. . . Explanation: For cos 225 degrees, the angle 225° lies between 180° and 270° (Third Quadrant).

What is the exact value of tan 255 degrees?

3.7321
Tan 255 degrees is the value of tangent trigonometric function for an angle equal to 255 degrees. The value of tan 255° is 2 + √3 or 3.7321 (approx).

How do you find tan 150 without a calculator?

Explanation: For tan 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant). Since tangent function is negative in the second quadrant, thus tan 150° value = -1/√3 or -0.5773502. . .

What is the exact value of tan135?

-1
FAQs on Tan 135 Degrees Tan 135 degrees is the value of tangent trigonometric function for an angle equal to 135 degrees. The value of tan 135° is -1.

What is the exact value of tan π?

0
The value of tan pi is 0. Tan pi radians in degrees is written as tan ((π) × 180°/π), i.e., tan (180°).

Why is tan150?

How to find the value of Tan 225?

On the trig unit circle, tan 225 = tan (45 + 180) = tan 45 = 1.

How to write tan ( 225 ) in Microsoft Excel?

225 is an obtuse angle since it is greater than 90°. tan(225) = 1. In Microsoft Excel or Google Sheets, you write this function as =TAN(RADIANS(225)) Since 225° is less than 90, we can express this in terms of a cofunction.

What is the value of the angle of 225 degrees?

The angle of 225 degrees lies in the third quadrant and its value is 225–180 = 45 degrees below the x-axis. Sine 45 in the third quadrant = (-1/2^0.5). Cosine 45 in the third quadrant = (-1/2^0.5). Tangent 45 in the third quadrant = +1.

How to evaluate the sine, cosine and tangent of 225 degrees?
