WebUsing trigonometry formula, the value of sin 420° can be given in terms of other trigonometric functions as: ± √ (1-cos² (420°)) ± tan 420°/√ (1 + tan² (420°)) ± 1/√ (1 + cot² (420°)) ± √ (sec² (420°) - 1)/sec 420° 1/cosec 420° ☛ Also check: trigonometric table How to Find the Value of Sin 420 Degrees? Web2) Arcsin is restricted to the 1st and 4th quadrant because the value of sine goes from all possible values that way. Think about the unit circle. In quadrants 1 and 2 sin will have the same value. An example being: sin(0) = sin(pi) = 0. But, if you take quadrants 1 and 4, then the sin function hits all possible values.
