θ° θradians cot(θ)
135° 3π/4 -1
150° 5π/6 -√3
180° π N/A
210° 7π/6 √3

What is cot value?

the price of cot thetha is sin thetha/ cos thetha. or.. 1/tan thetha… it is base / perpendicular too.

What is the price of cot Three pi by 2?

as an alternative. As you’ll be able to see, sin(3π2)=−1 and cos(3π2)=0 . Thus, cot(3π2)=0−1=0

What is the actual value of sin 3pi 2?

2 Answers By Expert Tutors pi, as a symbol, is thought to be a precise price; whereas 3. from the calculator is thought to be an approximate value. (0,-1) = (cos(3pi/2),sin(3pi/2)). So –1 = sin(3pi/2). 3∏/2 is 270 °, and is situated on the end of the third quarter, and starting of 4th quarter on unit circle

What is the actual price of sin 270?


What is sin a B sin AB?

The same old components for sin(A+B) is: sin(A+B)=sin(A)cos(B)+cos(A)sin(B) Now sin(−B)=−sin(B) and cos(−B)=cos(B) , so. sin(A−B)=sin(A)cos(B)−cos(A)sin(B)

What is the precise value of sin 360?

θ sin θ cos θ
90° 1 0
180° 0 −1
270° −1 0
360° 0 1

What is the exact worth of sin 300 levels?

Important Angle Summary

θ° θradians sin(θ)
270° 3π/2 -1
300° 5π/3 -√3/2
315° 7π/4 -√2/2
330° 11π/6 -1/2

What is the worth of sin 150?

The value of sin 30 levels and sin One hundred fifty levels are equivalent. Both are equal as a result of the reference angle for 150 is equivalent to 30 for the triangle formed in the unit circle. The reference angle is shaped when the perpendicular is dropped from the unit circle to the x-axis, which paperwork a proper triangle.

How do you in finding cos180?

To find the price of cos A hundred and eighty levels from the Cartesian airplane, the value One hundred eighty level takes position in the 2nd quadrant. As the cosine values in the 2nd quadrant always take a unfavorable price. From the worth of cos 0, we can download the price of cos 180°. It is additionally represented in terms of radians.

How do you to find the worth of sin 90?

Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the price of y becomes 1 since it touches the circumference of the circle. Therefore the worth of y becomes 1. Therefore, sin Ninety degree equals to the fractional price of 1/ 1.

What does Sine mean?

In arithmetic, the sine is a trigonometric serve as of an attitude. The sine of an acute angle is outlined in the context of a proper triangle: for the specified attitude, it is the ratio of the period of the side that is reverse that perspective, to the length of the longest side of the triangle (the hypotenuse).

Is Cos Sin Tan?

The tangent of x is outlined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is outlined to be the cosine of x divided by way of the sine of x: cot x = cos x sin x .

What is the method of 1 cos theta?

(Math | Trig | Identities)

sin(theta) = a / c csc(theta) = 1 / sin(theta) = c / a
cos(theta) = b / c sec(theta) = 1 / cos(theta) = c / b
tan(theta) = sin(theta) / cos(theta) = a / b cot(theta) = 1/ tan(theta) = b / a
