Find the 270 degrees value for all the trigonometric angles

We have to find the value of 270 degrees for all the trigonometric angles

Solution

Given below is the value of 270º for all the trigonometric ratios

sin 270° = sin (3 × 90° + 0°) = – cos 0° = – 1
cos 270° = cos (3 × 90° + 0°) = sin 0° = 0
tan 270° = tan (3 × 90° + 0°) = – cot 0° = Undefined
csc 270° = csc (3 × 90° + 0°) = – sec 0° = – 1
sec 270° = sec (3 × 90° + 0°) = csc 0° = Undefined
cot 270° = cot (3 × 90° + 0°) = – tan 0° = 0
