How do you find the reference angle of COS 135?
find cos(-135 degrees) We know that -135 degrees (going clockwise) is the same as 225 degrees (going counterclockwise). This lies in the 3rd quadrant. Taking the nearest x-axis, we find the reference angle to be 45 degrees.
How do you find the value of tan 135?
To find the value of tan 135 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 135° angle with the positive x-axis.
- The tan of 135 degrees equals the y-coordinate(0.7071) divided by x-coordinate(-0.7071) of the point of intersection (-0.7071, 0.7071) of unit circle and r.

How do you find tan 135 without a calculator?
Tan 135 Degrees Using Unit Circle
- Rotate ‘r’ anticlockwise to form 135° angle with the positive x-axis.
- The tan of 135 degrees equals the y-coordinate(0.7071) divided by x-coordinate(-0.7071) of the point of intersection (-0.7071, 0.7071) of unit circle and r.
How do you solve tan 315?
To find the value of tan 315 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 315° angle with the positive x-axis.
- The tan of 315 degrees equals the y-coordinate(-0.7071) divided by x-coordinate(0.7071) of the point of intersection (0.7071, -0.7071) of unit circle and r.
What is the formula of tan 135 degree?
The value of tan 135 degrees is -1. Tan 135 degrees in radians is written as tan (135° × π/180°), i.e., tan (3π/4) or tan (2.356194. . .).
How do you find Sec 135 degrees?
The value of sec 135 degrees can be calculated by constructing an angle of 135° with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of sec 135° is equal to the reciprocal of the x-coordinate(-0.7071). ∴ sec 135° = -1.4142.
