sin, cos and tan
They may be defined as the ratios of the lengths of sides of a right angled triangle, relative to either of the other angles.sine = opposite/hypotenusecosine = adjacent/hypotenusetangent = opposite/adjacentcosecant = hypotenuse/oppositesecant = hypotenuse/adjacentcotangent = adjacent/opposite.
ratios that r the same
When two ratios form a proportion, the ratios are equal
The ratios are not equal.
No
equivalent ratios
It would depend on which religion you are referring to.
It is a part of an expression related to ratios.
It is a trigonometric function, equivalent to the sine of an angle divided by the cosine of the same angle.
It you mean 16/10 then it is 8/5
If you mean: 4 and 20 then the ratio is 1 to 5
If you mean 5 and 7 then it is 10 and 14
