How do you find the value of cos 270?

How to Find the Value of Cos 270 Degrees? The value of cos 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of cos 270° is equal to the x-coordinate (0). ∴ cos 270° = 0.

How do you find the value of tan 30?

Since the tangent function is a periodic function, we can represent tan 30° as, tan 30 degrees = tan(30° + n × 180°), n ∈ Z. ⇒ tan 30° = tan 210° = tan 390°, and so on. Note: Since, tangent is an odd function, the value of tan(-30°) = -tan(30°).

What is the formula of tan 45 a?

Answer: Hence Proved that tan(45°+A) – tan(45°- A) / tan(45°+A) + tan(45°-A) = 1/sin2A.

How do you find tan 45?

In order to find out the tangent value of 45 degrees, we need to divide the opposite side to the angle by the adjacent side. Since both the opposite and adjacent sides of this triangle are the same, we can see that tan(45) is equal to 1.

Is tan 45 whole number?

According to sexagesimal system, it is written as ⁡ in mathematics. The value of tan of angle degrees is equal to exactly and also an integer.

What is the value of cosec pi minus theta?

cosec(π−θ)=cosec θ

Is cosecant undefined at pi?

Cosecant is the reciprocal of sine, so the cosecant of any angle x for which sin x = 0 must be undefined, since it would have a denominator equal to 0. The value of sin (pi) is 0, so the cosecant of pi must be undefined.

What is the value of sin 270 in fraction?

What are the sine and cosine of − 270?

If this is the case, then at 90 degrees, we will intersect the unit circle at the point (0,1), and at 270 degrees we will be at (0,−1) . Given that, we can easily find the sine and cosine: sin(270o)=−1,cos(270o)=0,tan(270o)=−10= undefined.

How do you find the value of cos 3pi?

The value of cos 3pi can be calculated by constructing an angle of 3π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 3pi is equal to the x-coordinate (-1). ∴ cos 3pi = -1.
