Sin 45
The negative solution is rejected because $45 \degrees$ is an acute angle and Sine of Acute Angle is Positive. Therefore: $\sin 45 \degrees = \dfrac 1 {\sqrt 2} = \dfrac {\sqrt 2} 2$ $\blacksquare$ Also presented as. Some sources present this result as: $\sin 45 \degrees = \dfrac 1 {\sqrt 2}$ SourcesTo convert degrees to radians, multiply by π 180° π 180 °, since a full circle is 360° 360 ° or 2π 2 π radians. The exact value of cos(45) cos ( 45) is √2 2 2 2. Multiply √2 2 ⋅ π 180 2 2 ⋅ π 180. Tap for more steps...

The exact value of cos 45 degrees is 1/√2 (in surd form), which is also equal to sin 45 degrees. It is an irrational number, equal to 0.7071067812… in decimal form. The approximate value of cos 45 is equal to 0.7071. Cos 45° = 1/√2 = √2/2. Therefore, 0.7071 or 1/√2 is a value of a trigonometric function or trigonometric ratio of ...cos 45° = √ (2)/2. cos 45 degrees = √ (2)/2. The cos of 45 degrees is √ (2)/2, the same as cos of 45 degrees in radians. To obtain 45 degrees in radian multiply 45° by π / 180° = 1/4 π. Cos 45degrees = cos (1/4 × π). Our results of cos45° have been rounded to five decimal places. If you want cosine 45° with higher accuracy, then ...
