Using this sine calculator, you can simply calculate the sine value of given angle theta.

Sine of angle is one among the three trigonometric ratios. The sine of an angle **‘α**‘ is defined as the ratio between the opposite side **‘a’** and the hypotenuse **‘c**‘.

**sin (α)= opposite/ hypotenuse = a/c**
