What is sin equal to? Sin is a dimensionless amount, that measures the size of the inclination of an angle with respect to the horizontal reference, where the adjacent side is sitting. When sin is zero, then the angle is zero, so there is no opening. The maximum opening of the angle ...
Method to Derive Sin 90 deg Value Let us calculate the Sin 90 deg value through the unit circle. The circle drawn below has radius 1 unit and the center of the circle is a place in origin. As we know Sine function is equal to the ratio of the length of the opposite side or perpend...

You might be curious how to find the sine of an angle. Use the formula below to calculate sin. Sine Formula The sine formula is: sin(α) =opposite/hypotenuse=a/c Thus, the sine of angle α in a righttriangleis equal to the opposite side’s length divided by the hypotenuse. ...
Answer to: sin 30 degrees is equal to which of the following: a) cos 30 degrees b) sin 60 degrees c) tan 60 degrees d) cos 60 degrees By...
Since for a right triangle the longest side is the hypotenuse and it is opposite to the right angle, the sine of a right angle is equal to the ratio of the hypotenuse to itself, thus equal to 1. You can use this sine calculator to verify this. A commonly used law in trigonometry ...
We have to analyse the problem as to how we can write standard angles such as 180 in terms of the 18. Here, we can write 18 in terms of 90 since sin 90 will be equal to 1. This step is followed in order to simplify the solution. ...
When the sine of y is equal to x: siny=x Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: arcsinx= sin-1(x) =y See:Arcsin function Sine table x (°) x (rad) sin x -90°-π/2-1 ...
