Find the trigonometric functions of :
−270°
Advertisements
उत्तर
Angle of measure (– 270°):
Let m∠XOA = −270°
Its terminal arm (ray OA) intersects the standard unit circle at P(0, 1).
∴ x = 0 and y = 1
sin (– 270°) = y = 1
cos (– 270°) = x = 0
tan (– 270°) = `y/x = 1/0`,
which is not defined.
cosec (–270°) = `1/y = 1/1` = 1
sec (–270°) = `1/x = 1/0`,
which is not defined
cot (–270°) = `x/y = 0/1` = 0
