Using unit circle cos 3pi/4 in terms of trigonometric functions using trigonometry formulas, we can represent the cos 3pi/4 as: Calculate 3 sec(3π/4) determine quadrant: 135 is an obtuse angle since it is greater than 90° sin(3π/4) = √ 2 /2 multiply our answer by our coefficient of 3
Note The X And Y Axis Are Included When Counting By Π/4.
Since our angle is greater than π/2 and less than or equal to π radians, it is located in quadrant ii in the second quadrant, the values for sin are positive only. Make the expression negative because cosine is negative in the second quadrant. Find the value using the unit circle cos ( (3pi)/4) cos ( 3π 4) cos ( 3 π 4) find the value using the definition of cosine.
Substitute The Values Into The Definition.
