Answer:
Step-by-step explanation:
cos(270°) = 0
sin(270°) = -1
tan(270°) = does not exist
cos(0°) = 1
sin(0°) = 0
tan(0°) = 0
Have a good day
The values of each trigonometric function are; cos(270°) = 0; sin(270°) = -1; tan(270°) = ∞; cos(0°) = 1; sin(0°) = 0; tan(0°) = 0
From definition of unit circle, angle in standard position and trigonometric functions, we derive the following trigonometric functions:
sin θ = y
cos θ = x
tan θ = y/x
Now, we know that;
An angle of 0° is found when x is greater than 0 and y is equal to zero.
An angle of 270° is found when x is equal to zero and y is less than zero.
Thus, the values of each trigonometric function are;
cos(270°) = 0
sin(270°) = -1
tan(270°) = ∞
cos(0°) = 1
sin(0°) = 0
tan(0°) = 0
