Sin 45 ratio
The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. For angles outside of this range, trigonometric values can be found by applying the reflection and shift identities. In the table below, stands for the ratio 1:0. These values can also be considered to be undefined (see division by zero). Webb23 aug. 2012 · sin 45 = cos 45 sin60 = cos 30 sin 90 = cos 0 Hence, all the cos values can be filled now. We know that tan = (sin )/ (cos ) Hence, all the tan values can be obtained …
