How is tan180 calculated?
How is tan180 calculated?
Using trigonometry formulas, we can represent the tan 180 degrees as: sin(180°)/cos(180°) ± sin 180°/√(1 – sin²(180°)) ± √(1 – cos²(180°))/cos 180°…We can use trigonometric identities to represent tan 180° as,
- cot(90° – 180°) = cot(-90°)
- -cot(90° + 180°) = -cot 270°
- -tan (180° – 180°) = -tan 0°
How do you find the value of sin 270?
⇒ 270 degrees = 270° × (π/180°) rad = 3π/2 or 4.7123 . . . Since the sine function is a periodic function, we can represent sin 270° as, sin 270 degrees = sin(270° + n × 360°), n ∈ Z. ⇒ sin 270° = sin 630° = sin 990°, and so on. Note: Since, sine is an odd function, the value of sin(-270°) = -sin(270°).
How do you find the value of cos120?
The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 120° is equal to the x-coordinate (-0.5). ∴ cos 120° = -0.5.
