What is the value of cos(pi/4)? - Socratic
2018年4月13日 · As you can see in the table above, cos45∘ or cosπ 4 radians is the same thing as √2 2. An alternative way is looking at the unit circle: We know that the cosine of an angle is the x -value of a coordinate. At π 4, we can see that the x -value is √2 2. Therefore, cos(π 4) = √2 2. Hope this helps!

Cos π/4 – Cosπ/4 Value – What is the cos of π/4 radians?
The cos of π/4 radians is √(2)/2, the same as cos of π/4 radians in degrees. To change π/4 radians to degrees multiply π/4 by by 180° / $\pi$ = 45°. Cos π/4 = cos 45 degrees. Our results of cosπ/4 have been rounded to five decimal places.
How do you find exact value of #cos (pi/ 4)#? - Socratic
2016年4月4日 · How do you find exact value of cos(π 4)? Let's first convert to degrees. The conversion ratio between degrees and radians is 180 π. π 4 × 180 π = 45∘. Now, we must think of the special triangle that contains a 45∘ angle. This would be the following triangle. The definition of cos is adjacent/hypotenuse. Therefore, our ratio is 1 √2.
