Inverse Trigonometry Formulas. sin-1 (–x) = – sin-1 x; cos-1 (–x) = π – cos-1 x; tan-1 (–x) = – tan-1 x; cosec-1 (–x) = – cosec-1 x; sec-1 (–x) = π – sec-1 x; cot-1 (–x) = π – cot-1 x; What is Sin 3x Formula? Sin 3x is the sine of three times of an angle in a right-angled triangle, which is expressed as:
A trigonometric number is a number that can be expressed as the sine or cosine of a rational multiple of π radians. [2] Since sin ( x ) = cos ( x − π / 2 ) , {\displaystyle \sin(x)=\cos(x-\pi /2),} the case of a sine can be omitted from this definition.
The value of sine varies as the angle between the base and hypotenuse of a right-angled triangles changes. The commonly used values of the sine are: sin 0 = 0, sin π/6 = 1/2, sin π/4 = 1/√2, sin π/3 = √3/2, and sin π/2 = 1. We can determine these values using the sine formula given by, sin x = Perpendicular/Hypotenuse.
26 maj 2024 · With this sin calculator, you can find the sine value in the blink of an eye – all you need to do is typing the angle in degrees or radians. The calculator also works the other way round – put the value of sine into the proper box, and we'll calculate the angle for you – isn't that awesome?
