How do you find the exact value of sin?
To remember the trigonometric values given in the above table, follow the below steps:
- First divide the numbers 0,1,2,3, and 4 by 4 and then take the positive roots of all those numbers.
- Hence, we get the values for sine ratios,i.e., 0, ½, 1/√2, √3/2, and 1 for angles 0°, 30°, 45°, 60° and 90°
- Now, write the values of sine degrees in reverse order to get the values of cosine for the same angles.

What is the exact value of 5pi 4?
Explanation: sec(5π4)=1cos(5π4) .Mar 19, 2016
Is sin 5pi 4 positive or negative?
Algebra Examples 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 third quadrant. The exact value of sin(π4) sin ( π 4 ) is √22 .
How do you convert 5pi 4 to degrees?
ad=54π⋅180°π=225° .Apr 19, 2015
How do you evaluate sin 5pi?
The value of sin 5pi can be calculated by constructing an angle of 5π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of sin 5pi is equal to the y-coordinate (0). ∴ sin 5pi = 0.
What is the exact value for tan?

What is 9pi 4 on the unit circle?
The value of sin 9pi/4 can be calculated by constructing an angle of 9π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (0.7071, 0.7071) on the unit circle. The value of sin 9pi/4 is equal to the y-coordinate (0.7071). ∴ sin 9pi/4 = 0.7071.
How to Find the Value of Sin 5pi/4?
The value of sin 5pi/4 can be calculated by constructing an angle of 5π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, -0.7071) on the unit circle . The value of sin 5pi/4 is equal to the y-coordinate (-0.7071). ∴ sin 5pi/4 = -0.7071.
