What is the Value of Sin 5pi/4? The value of sin 5pi/4 in decimal is -0.707106781. . .. Sin 5pi/4 can also be expressed using the equivalent of the given angle (5pi/4) in degrees (225°).

What is the exact value of 5pi 4?

Explanation: sec(5π4)=1cos(5π4) .

What is the angle 5pi 4?

ad=54π⋅180°π=225° .

What is value of sin 5pi?

The value of sin 5pi is equal to the y-coordinate (0). ∴ sin 5pi = 0.

What is the value of cos 55 by 4?

∴ cos 5pi/4 = -0.7071.

What is the exact value of cot 7π 4?

The value of cot 7pi/4 is -1. Cot 7pi/4 radians in degrees is written as cot ((7π/4) × 180°/π), i.e., cot (315°).

What is the exact value of 5pi 6?

Make the expression negative because secant is negative in the second quadrant. The exact value of sec(π6) sec ( π 6 ) is 2√3 . Multiply 2√3 by √3√3 .

How do you solve tan 5pi 3?

For tan 5pi/3, the angle 5pi/3 lies between 3pi/2 and 2pi (Fourth Quadrant). Since tangent function is negative in the fourth quadrant, thus tan 5pi/3 value = -√3 or -1.7320508. . . Since the tangent function is a periodic function, we can represent tan 5pi/3 as, tan 5pi/3 = tan(5pi/3 + n × pi), n ∈ Z.

What quadrant is 5pie over 4 in?

The angle is in the third quadrant.

What is the value of sin 5π 12 *?

The value of sin 5pi/12 is 0.9659258. . .. Sin 5pi/12 radians in degrees is written as sin ((5π/12) × 180°/π), i.e., sin (75°).

How do you find the value of sin 5pi 2?

1 Answer. sin(5π2)=1 , cos(5π2)=0 , tan(5π2)=∞ , cot(5π2)=0 , sec(5π2)=∞ and csc(5π2)=1 .

What is the value of Cos inverse Cos 5pi by 4?

Therefore, the value of cos–1(cos(5π4) ( 5 π 4 ) ) is 3π4.

How do you find the value of cos 5pi?

Answer: Since we are considering a unit circle the value will be negative one. Negative sign is used because π lies on the negative x-axis. Therefore,cos5π=−1 .
