Trigonometric functions: sine of the angle
Why do you need to know the value of the sine? Imagine a situation: one of the angles (A=60⁰) inscribed in a right triangle and the hypotenuse length are known. There is no other information. It is necessary to calculate the distant leg to the angle (A) leg. How to proceed?
The situation is very simple: look at the Bradis tables, find the value sin(60⁰)=0.866, substitute the data into the trigonometric function formula and solve the linear equation. From the school course, it is known that sin the angle – is the ratio of the distant leg to the angle, in this case A=60⁰, the leg to the hypotenuse.
It is simpler to perform all calculations using the online calculator on the site. This way, one can calculate the length of any side of a right triangle. Knowing the angle – means we know sin this angle. Conversely, knowing sin – finding the angle is not a problem.
